editor: Fix punctuation in JSX tags breaks the linked edit to the closing tag (#30167)

Closes #29983

While we only care about `.`, just enabling punctuation in case of
linked edits shouldn't hurt.

Release Notes:

- Fixed JSX component names with periods (e.g., <Animated.View>) now
maintain linked edits between opening and closing tags.
