🎨 style(issue_template): add prefixes to issue titles

Add prefixes to issue titles to improve consistency and make it easier to identify the type of issue.

- `[FEAT]` for feature requests
- `[QUESTION]` for questions

Also, update the bug report template to move the instructions for finding the app version to a markdown section and remove the placeholder text from the version input field. This makes it clearer and easier to follow the instructions.
