Fix: Comment shortcut in Svelte files now respects if the line(s) are HTML vs JS/TS (#5860)

Chase Weaver created 

Release Notes:

- Fixed: When using the comment shortcut, previously HTML or JS/TS would
all prefix lines with `// `. This PR brings the comments inline with
what is expected (`// ` for JS/TS, `<!-- ... -->` for HTML). Fixes
[#4578](https://github.com/zed-industries/zed/issues/4578).
