Support "No team" for policies

[jacobshandling]

@noahtalerman: YAML files reference doc updates are here: #22307

---

Flows to include in QA (non-exhaustive):

• On another page, switch to all teams –> go to Policies page, ensure No teams maintained
• Start on Policies page, select No team, navigate to another no-team supported page (e.g. Hosts), navigate back, ensure No teams selection maintained
• Select 'No team', then:
  • Create a new policy, ensure successful team assignment (0)
  • Create a new custom policy, ensure successful team assignment (0)
  • Edit existing No-teams policy, ensure success
  • Delete existing No-teams policy
  • Policy automation install software for a no-team policy. (Jacob did this during sprint demos, but since this is the main use case for this feature, worth checking again)

Breaking these subtasks out into their own story as they are not directly coupled with their original parent story #19551

@zayhanlon Just wanted to make sure you know that we are building support for "No teams" in policies to enable customer-preston to use for automated software install.

Hey @lucasmrod thanks for opening this PR to update the YAML files reference docs!

When you get the chance, can you please check if there are any other reference docs (maybe API) that need to be updated? Thanks :)

Hey @lucasmrod now that 4.57 is shipped, when you get the chance, can you please open a PR against the fleetdm/fleet-gitops repo to add a template teams/no-team.yml file?

Also, can you please check if there are any other reference docs (maybe API) that need to be updated? Thanks :)

Sounds good. Do we want to add sample software+policies yaml on fleet-gitops too?

Guiding through a cloud city,
Fleet's path now refined.
