ci(bot): add issue bot

New Pull Request Checklist

• I am not disclosing a vulnerability.
• I am creating this PR in reference to an issue.

Issue Description

Adds issue assistance when opening / reopening / editing a new issue.

Closes #7522

Approach

This is a custom bot, not to be published to the GitHub Actions Marketplace, currently with the following basic features:

• Checks only issues, not PRs
• Runs when opening / reopening / editing a new issue
• Ensures top checkboxes are checked
• Ensures issue template for bug / feature is used
• Contains a "beta" note at the bottom, so that readers know it may not interpret the issue always correctly
• Runs independently of existing CI, so should not influence it in any way
• Costs 10 seconds GH Actions processing time per run --> that should be monitored, but given the other long CI runs, it is maybe negligible
• Yes, I did name the bot Parsy (should probably remove that)

Here are some test issues to play around with and see the bot in action.
Simply toggle the checkboxes and wait 10 sec to see the bot message changing.

• New Feature: New Feature / Enhancement mtrezza/test#17
• New Issue: New Issue mtrezza/test#18
• Issue with template removed: No Template mtrezza/test#19

Screenshots

• Incorrect template:
  

• Not all checkboxes checked:

Notes

• Points to main branch of parse-issue-bot repo at the moment, because there will likely be rapid improvements needed during the beta rollout
• GH Action is not configurable via YAML parameters, template references are hardcoded, so if a template headline changes, the bot would have to change too. That can be improved, but I would only run this for dashboard and parse server to start with, they share the same templates.

Awesome work @mtrezza. I'm not overly familiar with the source code of custom GH Actions so someone with specific expertise might need to look over this.

Thanks for your great work!!
