build(deps-dev): bump apollo-server-testing from 2.11.0 to 2.16.1 in /backend

Sourced from apollo-server-testing's changelog.

v2.16.1

• This release only includes patch updates to dependencies.

v2.16.0

• apollo-server-fastify: Pass Fastify's request and reply objects into the context function, which previously had been receiving nothing. [Issue #3156](apollographql/apollo-server#3156) [PR #3895(apollographql/apollo-server#3895)
• apollo-server-lamdbda: Automatically decode payloads which are Base64-encoded when the isBase64Encoded boolean is present on Lambda event payloads. [PR #4311](apollographql/apollo-server#4311)

v2.15.1

• The default branch of the repository has been changed to main. As this changed a number of references in the repository's package.json and README.md files (e.g., for badges, links, etc.), this necessitates a release to publish those changes to npm. [PR #4302](apollographql/apollo-server#4302)

v2.15.0

• apollo-engine-reporting: Added a reportTiming API to allow trace reporting to be enabled or disabled on a per request basis. The option takes either a boolean or a predicate function that takes a GraphQLRequestContextDidResolveOperation or GraphQLRequestContextDidEncounterErrors and returns a boolean. If the boolean is false the request will not be instrumented for tracing and no trace will be sent to Apollo Graph Manager. The default is true so all traces will get instrumented and sent, which is the same as the previous default behavior. [PR #3918](apollographql/apollo-server#3918)
• apollo-engine-reporting: Removed GraphQLServerOptions.reporting. It isn't known whether a trace will be reported at the beginning of the request because of the above change. We believe this field was only used internally within Apollo Server; let us know if this is a problem and we can suggest alternatives. Additionally, the field requestContext.metrics.captureTraces is now initialized later in the request pipeline. [PR #3918](apollographql/apollo-server#3918)
• apollo-engine-reporting: Make Apollo Server throw if schema reporting is enabled for a gateway or federated service. [PR #4246](apollographql/apollo-server#4246)
• apollo-engine-reporting: Remove the experimental_ prefix from schema reporting options, and specifically rename experimental_schemaReporting option name to reportSchema. (The old option names remain functional, but are deprecated.) [PR #4236](apollographql/apollo-server#4236)

v2.14.5

• apollo-engine-reporting: Make Apollo Server throw if schema reporting is enabled for a gateway or federated service. [PR #4246](apollographql/apollo-server#4246)

v2.14.4

• apollo-engine-reporting: Add environment variable APOLLO_SCHEMA_REPORTING that can enable schema reporting. If experimental__schemaReporting is set it will override the environment variable. [PR #4206](apollographql/apollo-server#4206)
• apollo-engine-reporting: The schema reporting URL has been changed to use the new dedicated sub-domain https://edge-server-reporting.api.apollographql.com. [PR #4232](apollographql/apollo-server#4232)
• apollo-server-core: Though Apollo Server is not affected due to the way it is integrated, in response to an upstream security advisory for GraphQL Playground we have published the same patch on our @apollographql/graphql-playground-html fork and bumped Apollo Server to use it. Again, this was done out of an abundance of caution since the way that Apollo Server utilizes renderPlaygroundPage is not vulnerable as it does not allow per-request Playground configuration that could allow interpolation of user-input. [PR #4231](apollographql/apollo-server#4231)

v2.14.3

• This release only includes patch updates to dependencies.

v2.14.2

Note: This release is is related to a GitHub Security Advisory published by the Apollo Server team. Please read the attached advisory to understand the impact.

• ️ SECURITY: Pass all schema validation rules to the subscription server, including validation rules that restrict introspection when introspection is meant to be disabled. Read the full GitHub Security Advisory for details.
