Google Ads API versions are deprecated and sunsetted on a rolling ~12-month schedule, after which requests to sunsetted versions fail at runtime and break GoogleAdsIO. This workflow upgrades the version as new releases come out (roughly every three months) to prevent deprecation breakage.

Previous issues where this caused user impact: #37618 and #32241.
