fix(typescript-estree): fix more cases with double slash in JSX text

[duailibe]

This improves upon the commit 72552a3, catching more cases that needs to call rescanJsxToken(): after a closing element, after a self-closing element and after a JSX expression, when inside a JSX element.

Caught this with Prettier: prettier/prettier#6084

Fixes #606

LGTM, just one nit

I can't make CI green.. looks like there's some cache, it's not "seeing" the latest branch state

Nope, it was just me being dumb 😅
