tests: Remove "is proto fresh" test in lieu of GitHub Action (apollog…

…raphql#5031)

We'll have a GitHub Action do the maintenance on this file, rather than
having a test remind us that it's stale. The test results in all PRs
(and
all downstream users of this repository) suddenly getting failing tests
every time our infra-team deploys a new version of the proto, whereas
the
GitHub Action can be a much more controlled burn.

The GitHub action that replaces this is in [apollographql#5030], and we will merge
this test just as soon as that is validated.
