cli: allow supplying additional test file patterns to eslint-factory

[mtlewis]

Hey, I just made a Pull Request!

This addition makes life a little easier for folks using different test file patterns (e.g. putting tests or test support files in __tests__ directories), by allowing them to supply additional test file patterns when calling eslint-factory:

module.exports = require('@backstage/cli/config/eslint-factory')(__dirname, {
  testFilePatterns: ['src/**/__tests__/**']
});

@jhaals / @Rugvip I can take a look at doing this - it's a little more involved because it means we have to detect exclusion expressions and break them up in order to handle building absolute paths in the import/no-extraneous-dependencies rule. I think it's probably worth doing though, since right now the parameter won't work correctly with exclusions which could be surprising.

Just pushed 95cbc6de94 which makes the suggested change, including breaking up negations and converting them to absolute as expected.

Feeling we should move forward with #14065, alright to close this?

Works for me 👍
