Wagtail-meilisearch

Adds Django 4 support and compatibility with the latest meilisearch server (0.30.2) and meilisearch python (0.23.0)

Updates to work with latest meilisearch-python and latest Meilisearch. If you're upgrading, you'll want to delete the Meilisearch index and recreate it.

* Adds `QUERY_LIMIT` option to the config
* Allows latest version of `meilisearch` in the reqs

* Compatibility changes to keep up with MeiliSearch and meilisearch-python
* we've also switched to more closely tracking the major and minor version numbers of meilisearch-python so that it's easier to see compatibility at a glance.
* **Note**: if you're upgrading from an old version of MeiliSearch you may need to destroy MeiliSearch's data directory and start with a clean index.

* Adds the [delta update strategy](https://github.com/hactar-is/wagtail-meilisearch#delta-strategy)
* Adds the [SKIP_MODELS](https://github.com/hactar-is/wagtail-meilisearch#skip-models) setting
* Adds support for using boost on your search fields

This is probably the first release that I'd consider production ready.

Removes an unneeded import that I'd accidentally left in v0.1.3
