This reverts commit 902c49d1.

Reason for revert: Builders do not allow using a floating references. We need to start pinning tags to chromium/src again in order to run skew tests. The error can be seen here, https://logs.chromium.org/logs/chromium/buildbucket/cr-buildbucket.appspot.com/8863706392115604464/+/steps/test_pre_run/0/steps/s__trigger__weblayer_instrumentation_test_versions_apk_M88_Client_Tests/0/stdout?format=raw

Original change's description:
> weblayer, skew tests: Add M88 skew tests
>
> This skew test will updated daily by uploading new CIPD packages
> for each tag created in the M88 branch. The m88 reference will point
> to the most recent package uploaded.
