feat: support jsconfig.json files

[MichaelDeBoey]

Closes #51

[MichaelDeBoey]

@aleclarson Is there anything I still need to do in order to get this one merged?

[aleclarson]

Are you sure the upgrade to tsconfig-paths@4.0.0 is necessary here?

Also, the VSCode docs say this:

So you might need to check for jsconfig.json here:

vite-tsconfig-paths/src/index.ts

Lines 103 to 107 in 435077a

	let importerExtRE = /./
	if (!opts.loose) {
	importerExtRE = config.allowJs
	? /\.(vue|svelte|mdx|mjs|[jt]sx?)$/
	: /\.tsx?$/

…or else tsconfig-paths needs to set allowJs to true for us.

@aleclarson I think this one should be fine now?

Closing in favor of #57 since I don't have permission to push to your repo

Thanks for the contribution!

@aleclarson Edits by maintainers are enabled though on my branch, so you should be able to push new things 🤔

Must have been an issue with Codespaces :)

You'll still get credit from my PR
