cspell: ignore commonly ignored paths by default
Problem/Motivation
Suggested here #3405955: Add job for CSPELL in contrib pipeline.
Some files, like the composer.json file, contain usernames that are reported by cspell, so we should ignore them by default.
Core does that already: https://git.drupalcode.org/project/drupal/-/blob/11.x/core/.cspell.json?ref_type=heads#L6-41
Steps to reproduce
If you have your username in the composer.json file in the list of maintainers, and it is not a known word (eg: fjgarlin), the cspell job will report it.
Proposed resolution
Add a few sensible defaults to be ignored.
Remaining tasks
