meta: add Sentry.Extensions.AI to repository files

[Flash0ver]

Adding the brand new Sentry.Extensions.AI to these repository files:

• .craft.yml
• .github/ISSUE_TEMPLATE/bug_report.yml
• README.md

[Flash0ver]

question: Do we still need this file?

Sentry.Extensions.AI is already on NuGet.org.
And Sentry.Hangfire has been for almost 2 years.

I think it gets used when our release workflow runs, to publish new versions to nuget (otherwise nuget would be stuck on the current version that has been uploaded):
https://github.com/getsentry/craft?tab=readme-ov-file#craft-publish-publishing-the-release

We change this file so infrequently that I'm not sure though (I don't recall ever changing this file myself).
