🐛 Bug: pr-body-not-empty should filter out issue references

[JoshuaKGoldberg]

Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Expected

If someone puts an issue link like fixes #123 in their PR body, the pr-body-not-empty rule should not consider that a new word.

Actual

I'm seeing that it does. Putting a console.log({ uniqueWords }) in JoshuaKGoldberg/OctoGuideExamples#6:

{ uniqueWords: [ '2' ] }

Additional Info

Maybe the right resolution would be to ignore "words" that are just numbers?

I don't have a clear opinion on that. Somehow I think the current behavior is right.
