Enhancement: Self-updating embed of "good {first,intermediate,...} issues", "help wanted", or similar

[JacobCoffee]

Summary

Create an embed that can be posted to a channel like #good-first-issues or #available-issues, but also a callable through an app (slash) command e.g., /good-issues or similar.

Basic Example

• guild defineable, requires guild DB field
• On a scheduled task queue or on /good-issues slash command:
  • look up guild repo
  • find all "good first issue" (may need some type of fuzzy search here as labels are not the same everywhere)
  • generate shortlist of good issues that are not assigned

Drawbacks and Impact

No response

Unresolved questions

• for slash command, maybe allow users to specify a repo so they can generate a "good first issues from XYZ repo"
