I get the same warning. I also get errors about some rules not being found using typescript 3.7.5 and the base version.

@iamturns this issue is reintroduced when using a recent version on TypeScript (in my case 4.1.3).

Instead of bumping the (pinned) version of "@typescript-eslint/parser", would it not be better to make "@typescript-eslint/parser" a peer dependency (just like "@typescript-eslint/eslint-plugin", as described in issue #158)?
