In the current release process, we generate this file by using the actual formatters. Given that we aren't adding any new formatters, maybe it's not worth doing that....@eslint/eslint-tsc thoughts on that?

In the meantime, there are some linting errors in the file.

I agree. If it turns out at some point that it would be useful to autogenerate this page again, we could implement that later.

We also need this file.

I think we can just copy-paste that file from the current website:

https://github.com/eslint/website/blob/master/docs/user-guide/formatters/html-formatter-example.html

And we could keep the same structure:

docs/src/user-guide/formatters/index.md
docs/src/user-guide/formatters/html-formatter-example.html
