[Apps] Apps marketplace (first draft) (#17562)

https://github.com/user-attachments/assets/c4e63edb-6e98-44bc-841f-ee110ae712d4

How it works
- `manifest.json` files are now committed when apps are published to our
repo
- to display available apps, from the server, we read into our github
repo, using a pod-scoped cache
- feature flagged
- app installation will be behind permission gate MARKETPLACE_APPS

Limitations and what is yet to develop
- content and settings tabs
- installed apps tab
- app installation
- test and potentially fix reading from .manifest.json once [Reshape
manifest
structure](https://github.com/twentyhq/core-team-issues/issues/2183) is
done. additional work is expected on assets notably. (couldnt properly
do it here as manifest.json will only be committed after this pr)
- we only read in community/ folder for now - we may want tochange that
- the cache is rather artisanal for now and scoped by pod - we may want
to change that
