Rsync not working when using Docker - remove feature and update docs

When starting the recorder via docker and trying to use the archive option engine-recorder show the following error message:

engine-recorder  | 2024-01-18 11:54:56,487:Engine-Recorder:WARNING - Archiver: Could not run rsync:
engine-recorder  | rsync: [sender] Failed to exec ssh: No such file or directory (2)
engine-recorder  | rsync error: error in IPC code (code 14) at pipe.c(85) [sender=3.2.7]
engine-recorder  | rsync: connection unexpectedly closed (0 bytes received so far) [sender]
engine-recorder  | rsync error: error in IPC code (code 14) at io.c(231) [sender=3.2.7]

Proposal

As discussed below, we decided to remove the feature.

Sub Tasks

• Remove code relevant to archiving
• Documentation: Remove any mentions about that feature in README and docs.
• Provide Sample how admins can do their own rsyncing: https://docs.aura.radio/en/latest/administration/aura-recorder/install-manual.html#archive-recordings
• Update changelog
