* fix(ci): sentry is not longer being activated in test builds
This removes sentry from all the test execution, as some tests might fail as sentry wasn't initially built, or it might take more time to build as it will have to build with sentry.
* fix(build): workaround the failed to fetch oauth token error
* refactor(build): use better stage naming and document it
* refactort(build): use multiple cache sources
* docs(build): add a comment for cache
* fix(build): remove gcr.io as it does not supports OCI images
