fix: update community discussion link in output from cli - yarn rw upgrade

[jgal1]

This is a fix for (#11463) . This PR simply updates the dynamic url generated via the 'yarn rw upgrade' to a static url. The dynamic link yieled no results in a search. The updated url (https://community.redwoodjs.com/c/announcements/releases-and-upgrade-guides/) makes it easy to find the upgrade guide.

This is a quick fix. A better long term solution should link directly to the url for the specific version that was upgraded to, but that likely requires a lot more thinking about generating/standardizing the routes of the community docs themselves.

Test Plan:

Before the fix - run 'yarn rw upgrade' in any project and navigate to the link output by the cli (https://community.redwoodjs.com/search?q=8.0.0%23announcements). Observe a page with no results

After the fix - follow the steps to test the cli and navigate to the cli link where release notes are immediately found.

Not sure if I can fix the broken checks myself. It's probab\ly simple but I don't know how to add a label or if I have permission, nor what changesets are, I ran the yarn changesets command I get "No GitHub token found. Please set GITHUB_TOKEN or REDWOOD_GITHUB_TOKEN", I have ssh access to git via the terminal so not sure about that either. Same with the milestone. Please, advise if it is something I can fix by linking to docs or letting me know how. Thanks.

I didn't have permission to push to the fork to add the changelog entry. It's okay the title is clear enough to completely describe the change. I didn't work on that yarn changesets utility but I know I had to add a github token myself so it can reach out to the github api to fill in some of the details like pr title, number, author etc.

The labels are okay I can deal with those. I think they might have some permission requirements on them.
