Don't report API Keys as errors (#3438)

PBENCH-1168

Our API Key structure causes the primary OIDC key validation to fail with a
`ValueError` exception. This isn't caught by the handler, and propagates to
the caller's `except Exception` where it's reported as an error with
traceback, which we don't want for a routine key validation.

This just adds `ValueError` to the catch to avoid the annoying log message.
