Add support for `script setup`, new in Vue 3

[garyo]

Vue 3 has "script setup"; see https://v3.vuejs.org/api/sfc-script-setup.html#basic-syntax for info. This change updates the script regex to allow for script setup there.

The same line should also be added to const vue--front-tag-regex

I hope this PR will be released quickly.

@garyo Can you fix?

The same line should also be added to const vue--front-tag-regex

  (defconst vue--front-tag-regex
    (concat "<%s"                        ; The tag name
            "\\(?:"                      ; Zero of more of...
            "\\(?:\\s-+" vue--not-lang-key "[\"'][^\"']*?[\"']\\)" ; Any optional key-value pairs like type="foo/bar".
            ;; ^ Disallow "lang" in k/v pairs to avoid matching regions with non-default languages
            "\\|\\(?:\\s-+scoped\\)"      ; The optional "scoped" attribute
            "\\|\\(?:\\s-+module\\)"      ; The optional "module" attribute
            "\\|\\(?:\\s-+setup\\)"       ; The optional "setup" attribute
            "\\)*"
            "\\s-*>\n")                     ; The end of the tag
