📝 chore(github): add issue templates for bug report, feature request, and question

The issue templates for bug report, feature request, and question have been added to the `.github/ISSUE_TEMPLATE` directory. These templates will help standardize the information provided in issues and make it easier for contributors to provide the necessary information. The bug report template includes checkboxes to ensure that the FAQ has been checked and open issues have been searched before submitting a new bug report. The feature request template is a simple template for suggesting new ideas for the project. The question template asks for the version of Keepass2Android being used to help with troubleshooting.
