fix: enable JSX parsing inside .vue files

[ematipico]

Summary

Closes #3464

Test Plan

I would like to add a test, but I couldn't find a file on the web

Vue supports jsx when lang attribute set as such lang=jsx without it, parser error is thrown, see

Should we also enable it based on attribute?

I believe the original issue comes from a V2 Vue component, but I'm not sure. I'm waiting for OP to share their whole code

[minht11]

The problem enabling jsx on every vue file would that valid TS code like const fn = <T>() => {} would no longer be parsed correctly.

Wouldn't users need to add lang=ts in their <script> tag in order to do so?

[minht11]

Sorry if I am wrong, doesn't this PR changes behavior that lang='ts' is being parsed as tsx and lang=js as jsx?

[ematipico]

Ooooh, I see your point now! I'll fix it later

https://github.com/vuetifyjs/vuetify uses jsx/tsx a bunch, you could use those for tests
