Remove a Crowdin branch with the action

[NickVolynkin]

Is your feature request related to a problem? Please describe.

We want to create a Crowdin branch for each pull request. When the translation is done, we'll pull it, run the tests, and, finally, merge the pull request. Now it's time to remove the Crowdin branch. It would be nice to do so with this action.

Describe the solution you'd like
A configuration option to remove a named Crowdin branch or branches.

Describe alternatives you've considered

• manually removing branches — not acceptable
• using CLI for this particular task — requires making a custom Docker image, too much work for a single use
• dropping the action and running everything directly from the CLI
