Follow-up to https://github.com/discourse/discourse/pull/31271 In the linked PR, we made `<GroupChooser />` use the site's preloaded list of groups instead of fetching the list from the servers every time the component is triggered. However, when a site has thousands of groups, the performance issue has shifted from the server to the browser — `<GroupChooser />` takes several seconds to render in the browser for a site with thousands of groups and the sites becomes completely unresponsive while the component is rendering. This PR changes the `<GroupChooser />` so it limits the displayed groups to 100, with ability to filter the list to show more groups when there are more than 100 groups.
