Update nightly build job

- (Reland) Update CWS credentials: the OAuth OOB flow will be deprecated
  on October 3, 2022, so this CL adds regenerated credentials which use
  another flow to avoid the deprecation.
- (Reland) It also adds a suffix to the name of the secret to avoid name
  collision, since Zuul requires credential names to be unique
  throughout each tenant.
- The chrome-webstore-upload-cli package is bumped from 2.0.1 to 2.1.0.
- The job now uses the cws-upload and fetch-cws-upload-log roles in the
  common zuul/jobs repo (which have moved from this project to there so
  they can be used by other projects as well).
