HTML: comments inside a script tag no longer sensitive to script language

[bgashler1]

• VSCode Version: Insiders
• OS Version: Windows 10

Regarding test plan item #12100

Steps to Reproduce:

1. Select some JavaScript code inside of a <script> block in an HTML file*.
2. Use the keyboard shortcut to "Add a line comment" or run the command from the command palette.
3. Note that in the latest Insiders build, it no longer uses //``JavaScript-valid comments; instead, it now uses` comments.

Current Insiders

Current Stable

*I'm not sure, but this may apply to Handlebars and Razor also.

HTML has been extracted into a separate language server and this functionality has been lost. Moving to October.

We should document this limitation in the release notes.
