Describe the bug

In the Ory Helm Charts it is possible to set annotations on service accounts using the below syntax

deployment:
  serviceAccount:
    annotations:
      annotation/example: foobar

This behaviour isn't consistent within the hydra-maester and oathkeeper-maester, and you can't set annotations as required.

Reproducing the bug

Unable to set any custom annotations, as the option does not exist.
