[Core][UA] Forward-port 8.18 changes into main (#214996)

## Summary

We've done a lot of UA changes against 8.18 and 8.x but we did not port
them to `main`. The reason we did not do the active development against
`main` is because UA is disabled on main and we need those features in
8.last not on `9.0` initially. This port is to keep the codebase
consistent and to be able to use these new UA features in the future
post `9.0`.

Any issues that that are caused from this port we should wrap them in a
config and disabled them on main and enable this new flag on `8.x`.

What is being ported?
- [x] Upgrade assistant plugin
(`x-pack/platform/plugins/private/upgrade_assistant`)
- [x] Integration test changes
(`x-pack/test/upgrade_assistant_integration`)
- [x] new UA doc links
(`src/platform/packages/shared/kbn-doc-links/src/get_doc_links.ts`)
- [x] localization files sync
(`x-pack/platform/plugins/private/translations/translations/*.json`)
- [x] Unfreeze is no longer supported after `8.x`. So removed it from
data streams readonly migration step and throw an error for regular
indices migration.

Closes #210490

 request to a deprecated API. These are also generally surfaced as deprecation headers within the
 response. Even if the cluster state is good, app maintainers need to watch the logs in case
 deprecations are discovered as data is migrated. Starting in 7.x, deprecation logs can be written to a file or a data stream ([#58924](https://github.com/elastic/elasticsearch/pull/58924)). When the data stream exists, the Upgrade Assistant provides a way to analyze the logs through Observability or Discover ([#106521](https://github.com/elastic/kibana/pull/106521)).
