Subject: [PATCH] Add workflow for automatic issue deduplication (#41942)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request
Tested this in my fork, this'll run the dedup AI model on any new issue
that's been filed or re-opened. If it finds a duplicate, it'll label it
with "duplicate" and comment which issues it dupes to. This won't close
the issue.
