Limits / Keyword ID / Formating

[use-the-fork]

This PR includes:

Fixes:

• A bug where a limit wasn't being applied. @pdphilip, there's one TODO left for InnerHits.
• A bug where IDs were treated as integers instead of strings, though they are stored as keywords.

Adds:

• A GitHub workflow that auto-applies Pint formatting to PRs.
• A default pint.json file.
• A docker-compose file for setting up Elasticsearch in dev when not using Nix.

@use-the-fork - Limit-based tests are great.

Inner hits hard limit has been set back to the original logic as per the commit message. In doing so, I also reset the two limit type methods from the query builder to see which of the tests would fail, but they are passing and seem to work as expected. Have a look to see if there's been an edge case missed somewhere. If so, please add it to the new limit tests so I can see it first-hand. Else GTG.

New add-ons are great!

@pdphilip This looks good to me! I just tested as well and everything passed.
