[Backport release-0.9] fix(treesitter): redraw added/removed injections properly (#23408)
fix(treesitter): redraw added/removed injections properly

When injections are added or removed make sure to:
- invoke 'changedtree' callbacks for when new trees are added.
- invoke 'changedtree' callbacks for when trees are invalidated
- redraw regions when languagetree children are removed

(cherry picked from commit b68157834a)
