Fix regex to match on .js but not on .json

[abentkamp]

I ran into the following error when adding an npm package that attempted to import a json file:

✘ [ERROR] Expected ";" but found ":"

    node_modules/@leanprover/unicode-input/dist/abbreviations.json:2:8:
      2 │     "{}": "{$CURSOR}",
        │         ^
        ╵         ;

What's happening here is that vite tries to parse the json file as javascript and fails. The reason is that this plugin's regex matches .js but also .json. (I don't fully understand the details...) Anyhow, a $ at the end of the regex resolves the issue.

I encountered the same issue. I recommend addressing this bug fix as well.

We are hitting this issue in lean4monaco which effectively prevents us from using this package as is. Instead we default to using a modified copy with the change from this PR.

Since this looks like a very small diff, could I ask if there is anything which prevents this from being merged? Is there anything we could do to facilitate the bug fixing?

I have the same problem - I'm not fully understanding the need for this besides for the file node_modules/.vite/deps/assets/webWorkerExtensionHostIframe.html
