Update install-fleet-maintained-apps-on-macos-hosts.md
Added context for generated uninstall scripts for macOS and Windows.
@noahtalerman & @mostlikelee Created PR for the uninstall scripts documentation.
@eugkuo just a heads up that this PR has some merge conflicts that need to be resolved before we can merge.
@iansltx to help update this as he's rewritten the article.
@eugkuo I just looked at the revised article and realized that I changed the content that you were tacking this onto rather significantly, which is probably why Git marked this as a merge conflict vs. just saying "oh, that file is over here now and I can apply the same change."
Probably best to look at the state the article is in now and create another PR off of the revised version with appropriate wording if necessary; I actually removed the reference to where we get uninstall scripts from since it was Homebrew specific, so the article is now vague but not inaccurate.
Closing this as https://github.com/fleetdm/fleet/pull/28013 supercedes it.
