Fix JavaScript and TypeScript HTML injections (#16479)

Fixes #16199

## Description

Recently added template string injections do not completely work for
because any time there is an interpolation (`${// some js content}`)
within an element, its closing tag is not highlighted properly:

This PR fixes the issue:

Release Notes:

- Fixed incomplete syntax highlighting for HTML injections inside
JavaScript template tags.

## Note

I'm a beginner with treesitter so I only modified the part for HTML
usecase.
Should the same solution be applied to other injections (`css`, `js`,
etc.)?
