[vscode] Fix client_end highlighting.
Previously, client_end only highlighted properly if angle brackets were
used unconditionally. So `client_end:<Foo>` and `client_end:<Foo,
optional>` would highlight correctly, but `client_end:Foo` would break
syntax highlighting until a matching `<Foo>` or `<Foo, optional>` was
found.
