Re-sort diagnostics after transaction transform (#3895)
Applying document-change transactions to diagnostic ranges is not stable
with respect to the ordering of diagnostics. This can cause diagnostics
to become temporarily unordered with some edits to a document, which can
eventually break some invariants/assumptions in syntax::merge.
With this change, Document::diagnostics are always sorted.
