[FEAT] Add "Closes" prompt

Is your feature request related to a problem? Please describe

Often you need to reference an issue that is being closed by the commit. All major git hosting platforms have support for acting on the commit message:

• https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue
• https://docs.gitlab.com/ee/administration/issue_closing_pattern.html

Describe the solution you’d like

1. Add another prompt that requests to input a reference to an issue that is being closed.
2. Add another setting to configure the closing pattern prefix (e.g. Closes or Fixes).

Describe alternatives you’ve considered

Used another extension that has support for this, but was otherwise buggy.

Additional context

The final commit message shall look like:

feat: short description

Long description.

Closes: #123456789
