Update "subject updates" section of Working on Tickets Workflow

The following discussion from !81983 (merged) should be addressed:

• @lbot started a discussion:

  1. Ensure that the subject of a support ticket is both descriptive and accurate. You can edit the Subject to fix typos or make the problem clearer. some examples include:
  
  - gitlab error 500 on login -> gitlab error 500 on login due to no partition of relation "audit_events"
  - My Account was Blockes -> My Account was Blocked
  - git reconfigure with below errors -> git reconfigure with letsencrypt_certificate errors 
  

  We don't do this a lot -- 28 tickets had title updates in the last 30 days -- but I think showing examples may help uptick usage.
