**Related issue:** Resolves#35554
- Setup experience is generated to and can be set in the GitOps yaml
- No changes to policy creation, setup experience apps are still added
as `PREINSTALLED`
- API change: `GET /fleet/setup_experience/software` modified to be able
to take a comma separated list of platforms, like `GET
/fleet/setup_experience/software` does. Documentation update will be in
another PR.
- Modified `SetTeamVPPApps` to return if setup experience changed so the
function that calls it can create a "setup experience changed" activity.
# Checklist for submitter
## Testing
- [x] Added/updated automated tests
- [ ] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)
- [x] QA'd all new/changed functionality manually
- Used generate-gitops to create a yaml file, edited setup experience
apps with it to test that it applies and creates activities correctly.
- Re-enrolled an Android phone after editing setup experience with
GitOps, all setup experience apps were installed.
