I want to evaluate that pull request title contains issue key in other format

[Jorge Martinez]

I'm using pull request merged trigger to transition issues through the workflow. If I don´t include any validation, Jira trigger actions over issue keys that finds in pull request title and pull request comments or body so I include a validation over the pull request title to matches with issue key and it works. Now Im trying to make this validation even when pull request title contains issue key in other format like 'zzz 23' instead of 'ZZZ-23'
