The Google Workspace driver test broke after the dependabot
google.golang.org/api bump (v0.269.0 → v0.277.0): the recorded cassette
embeds X-Goog-Api-Client: gdcl/0.269.0, which the upgraded SDK no
longer sends, so the default matcher rejects every interaction.
Configure the matcher to ignore User-Agent and X-Goog-Api-Client so
cassettes survive client-library version bumps.
