With https://github.com/elastic/elasticsearch/pull/81870, the Azure, GCS, and S3 repository types have separate, dedicated pages in the Elasticsearch guide. For consistency, this PR creates separate pages for the shared file system, read-only URL, and source-only repository types.
Related changes:
- Adds redirects to the plugins docs
- Fixes a few breaking changes that refer to the Azure, GCS, and S3 repositories as plugins.

As of 8.0, the compatibility window for cross-cluster search (CCS) to an earlier release will be one minor release. This updates the CCS docs and adds a related 8.0 breaking change.
Closes https://github.com/elastic/elasticsearch/issues/80782
Combines several 8.0 breaking changes for the removal of API endpoints that contain mapping types. These items were separate because we previously organized breaking changes by area.
This is a follow-on to #79162.
The change removes a node-level setting. It was accidentally placed with REST API changes as part of https://github.com/elastic/elasticsearch/issues/79162. This moves the breaking change to the cluster and node setting changes section.
