Update fog-google gem to 1.14.0+

We need to update this dependency to at least 1.14.0 to unblock Ruby 3 support in GitLab.

Steps

• Replace gitlab-fog-google with latest upstream release
• Verify no build failures
• Verify no test failures
• Verify no lint failures
• Verify no regressions introduced

Regression testing

The following primary features should be regression tested:

• CI job logs. Especially incremental logging: https://docs.gitlab.com/ee/administration/job_logs.html
• File uploads.
  • Images
  • Attachments
  • CI artifacts
  • Git LFS objects
• Package publishing. At least via Maven.
• Rake tasks. Backups and repository cleanup.

The following internal library changes should be verified:

• Fix for handling of slashes in URIs (https://github.com/fog/fog-google/pull/530)
• Unlinking temporary files (https://github.com/fog/fog-google/pull/521)
