Remove links to reduce timeline noise

[landongrindheim]

🖼️ Context

In an attempt to reduce noise in timelines, I'm removing links to PRs opened by Dependabot. I've opted to leave non-bot contributors for now.

I also inserted a zero-width space between @ and handle in the release notes so as to limit notification noise. If this is unwelcome, please let me know 🙂

Closes #5639

@landongrindheim Not sure if this is helpful, but this is the original report with links with the fix that was implemented at the time: #3276.

It seems that we have regressed somewhere but I have no idea where or how. This PR seems like a workaround for now to stop the bleeding? I mean we always showed links, and GitHub didn't create cross references until now. With this solution, we would lose the links?

Thanks @deivid-rodriguez! I misread this report. Looking closer, it appears that we started spamming yesterday (Sept 5th):

That should help track this down.

The closes PR I see was the Rubocop Performance change, which was merged a few hours before these started appearing.

Could this be at all related to internal work on the monolith or api back end? I know some of the team was recently touching code around PR generation there... perhaps a side effect? Might want to circle up with them internally.

Looking closer, it appears that we started spamming yesterday (Sept 5th):

If you're referring to tc39/ecma262#2819, it's not that something in Dependabot changed at that time; rather, that's when the babel release which mentioned said PR went out.

Closing this as it did not address the intended issue
