`scanImportsFromDir` fails to detect `subdir/index.{tsx|jsx}` files

[aklinker1]

Environment

• Unimport: v3.7.1
• Node: v18.16.1

Reproduction

https://github.com/aklinker1/unimport-tsx-bug

pnpm i
node index.mjs

Describe the bug

When components/index.ts exports a subdirectory with a index.tsx file in it, an error is throw (see logs below).

https://github.com/aklinker1/unimport-tsx-bug/blob/56985dab7724fae0c3e28f3801d6b3297bb2eed3/components/index.ts#L1

Same error is thrown if the file is components/Iframe/index.jsx.

There is a work-around, change the export in components/index.ts:

-export * from "./Iframe";
+export * from "./Iframe/index.tsx";

Additional context

This issue originates from: https://github.com/wxt-dev/wxt/issues/440

I did some research into this and it appears we just need to add "tsx" and "jsx" to the file extensions array?

https://github.com/unjs/unimport/blob/8a622c9c38d28ee9a80e7c0b8cb82bea05a69766/src/scan-dirs.ts#L41-L48

#229 fixed this for non-JSX files.
