Changes

• Organisation, project and environment settings can be managed in a single place for users, groups and roles
• Edit permissions happens without needing to press save (suggested in UX audit). This will start becoming a standard pattern with settings.
• All users, regardless of their role can access the permissions screen, they can manage whatever they are admin of (e.g.permissions for a group on an environment they are admin of)
• Previously, you had to navigate to separate areas to manage a group's users and their permissions, this is now combined
• Create / updating group no longer requires a refresh
• Dev experience: Migrates all groups functionality and OrganisationProvider to TypeScript/RTK
• Dev experience: Removes /organisation-groups, this was a page we showed specifically for MANAGE_GROUPS users, it is no longer needed.
• Minor: Improves user list ui
• Minor: Toast messages no longer show duplicate consecutive messages

How I tested

• Created / edited a group
• Managed organisation, project and environment permissions as an org admin
• Checked I couldn't edit permissions as a group admin without org permissions
• Made group admin a project admin, checked that they could manage permissions but just for that project

Yep correct, remove-users calls were missing. I've since tested adding and removing group users.

Sorry, I think this is probably the last issue but it looks like we've lost the tags that we had previously on each of the entities that gave a summary of what permission a user had on that entity without having to open it up.

@kyle-ssg this looks good now (and seems to include the fix we talked about yesterday regarding showing the groups in a project settings) but I've updated the title of the PR as I don't think it should be a chore.
