Fix postrgres secret name for cronjob (#15072)
Fix postrgres secret name for cronjob (#15072)

The cronjob tries to get key from `mastodon` secret instead of
`mastodon-postgresql` - so the cronjob fails with this error:

Error: couldn't find key postgresql-password in Secret [NS]/mastodon

Another solution is to save the postgres password in mastodon secret,
but that means that the password is placed in two places.

Postgresql use <fullname>-postgresql name as secret name.
