fix: allow more characters in the unicode range as component identifiers

[dummdidumm]

fixes #13194

We narrowed the allowed characters in #13057, but didn't take into account all possible (and for JavaScript identifiers allowed) unicode characters. This widens that, which also removes the accidental breaking change (because in Svelte 4 you were allowed to use these unicode characters).
