feat: group format messages into one

[43081j]

Publint emits messages when you have ESM files in a CJS package but the
extension doesn't match.

For example, 'foo.js' in a CJS package which contains ESM should really
be foo.mjs.

This is often a very noisy message in a repo that matches it since its
usually the case that many files have this issue or none do.

This change basically groups them all up into one summary message so you
can investigate yourself.
