(GHA) Update casing and fix authorization (MicrosoftDocs#12253)

Prior to this change, the authorization parameter handling didn't
correctly handle an empty string for the `authorized_accounts`
parameter. The casing for all other workflows used incorrect
casing for workflow parameters, like `Message_Body` instead of
`message_body`.

This change:

- Corrects the casing of all parameter handler entries.
- Ensures that the parameter handler for `authorized_accounts`
  only passes the parameter to the action script when the
  input value is a non-empty string.
