percona: adapt upstream release model

In accordance to the upstream release cycle, we now provide 2 flavours
of the percona mysql ecosystem. The default is the LTS variant,
additionally there is now the floating `percona-server_innovation`
always pointing to the most recent regular release.

- mentioned in release notes
- adapted all depending tests and tools (xtrabackup)

 - `unrar` was updated to v7. See [changelog](https://www.rarlab.com/unrar7notes.htm) for more information.
 
+- `percona-server` now follows [the same two-fold release cycle](https://www.percona.com/blog/lts-and-innovation-releases-for-percona-server-for-mysql/) as Oracle MySQL and provides a *Long-Term-Support (LTS)* in parallel with a continuous-delivery *Innovation* release. `percona-server` defaults to `percona-server_lts`, will be backed by the same release branch throughout the lifetime of this stable NixOS release, and is still available under the versioned attribute `percona-server_8_0`.
+  The `percona-server_innovation` releases however have support periods shorter than the lifetime of this NixOS release and will continuously be updated to newer Percona releases. Note that Oracle considers the *Innovation* releases to be production-grade, but each release might include backwards-incompatible changes, even in its on-disk format.
+  The same release scheme is applied to the supporting `percona-xtrabackup` tool as well.
+
 - `git-town` was updated from version 11 to 13. See the [changelog](https://github.com/git-town/git-town/blob/main/CHANGELOG.md#1300-2024-03-22) for breaking changes.
 
 - `k9s` was updated to v0.31. There have been various breaking changes in the config file format,
