Bug: v6 eslint-plugin package doesn't allow v6 parser to satisfy peerDependency

[JoshuaKGoldberg]

Suggestion

Just filing an issue for tracking: #6630 fixes this.

After going through the steps in https://typescript-eslint.io/blog/announcing-typescript-eslint-v6-beta#trying-out-v6 to install the v6 package versions:

npm i @typescript-eslint/eslint-plugin@rc-v6 @typescript-eslint/parser@rc-v6 --save-dev

npm will give a complaint:

The problem is the @typescript-eslint/eslint-plugin package lists its @typescript-eslint/parser peerDependency as ^5.0.0. That doesn't allow for 6.x versions.
