%garden desk renaming

[~rilfun-lidlen]

Tlon will publish an update in the next few weeks to the %garden desk that will rename it to %landscape. We will also move or move-and-rename several agents from the Groups 1 and 2 desks.

You are impacted if your app relies on the following agents:
- %s3-store

- %settings-store

- %hark
