Don't fail Jira resolve/Done transition if it already happened (OSOE-489)

[Piedone]

When using post-pull-request-checks-automation, if you have multiple pull requests for a Jira issue, the one completing first will transition it, making the other one fail with something like:

Please specify transition name or transition id.
Possible transitions:
{ id: 201, name: Reopen } transitions issue to 'To Do' status.
Failed to transition issue.

See e.g. here. The step should not fail in such cases, and just do nothing if the issue is already in the target state.

The available transitions can be fetched via https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-transitions-get.

Will do as part of #277.
