Fix/api key auth version

[alifeee]

closes #1454

changing test-requirements.txt means that the tests for api_key auth do fail.

Adding the "fix" means the tests "work" (they do not throw an exception)

nice fix !

I noticed our test suite uses a different version for the google auth lib.

I coul add a new test in the CI that checks the version of the dependencies in the file pyproject.toml and in the test-requirements.txt file and ensures they are the same ! otherwise we forgot to update one or another.

I don't think this is necessary. After this PR, they will be the same.

If we update the version in pyproject.toml, it will be presumably because we had to (to fix something broken). When we fix it, the tests should break too (as they will be using an older version of auth libraries).

I will merge this 👍
