Update dependency @types/node to v16.11.9

Editor assessment

Bumping @nestjs/apollo from 10.0.14 to 10.0.16 names the package and both versions, with deps-dev correctly marking a development dependency. The body is the Dependabot template — release notes, commit comparison, structured metadata declaring a semver patch, and a Signed-off-by trailer — boilerplate yet well-formed and harmless; a patch bump of the GraphQL adapter needs no motivation. Hygiene is clean throughout: imperative subject, no trailing period, reasonable length, machine-readable footers, and no pasted diffs, logs, or junk tokens. The header fully identifies the change and the body only adds provenance.
