Allow linting of <script> section only if lang="ts"

[jez9999]

I'd like to be able to lint my .vue file script sections only if lang="ts". At the moment ESLint is linting script sections that are just plain JS (ie. <script setup>) as well as TS ones (<script setup lang="ts">) when I run eslint . --ext .vue --ignore-path .gitignore. A good solution would perhaps be to be able to say in .eslintrc.cjs which script section languages should be linted. Another solution would be to allow to set which rules get linted based on language; obviously certain TS rules I apply do not apply to plain JS because plain JS cannot set types.
