Add additional issue and pr automation

[jaydeluca]

Closes #9289

• For PRs that have been open for 1 year with no activity, mark as stale and add comment, close if still no activity after 7 days
• For issues with the tags: "enhancement" or "contribution welcome" that have no activity for 1 year, add a comment and a "needs author feedback" label
• For issues that have the "needs repro" label that have had no activity for 1 month, add "needs author feedback" label

if we wanted to take a more iterative approach, we could probably even start this at like 2 or 3 years, see what it yields, and then lower it until we get it to 365.

LGTM. I think this will help considerably with managing the volume. Thanks.

I'm looking forward to merging this, but also nervous, let's give it a spin in contrib first? open-telemetry/opentelemetry-java-contrib#2305
