Add support for TypeScript moduleResolution - bundler

[xeho91]

What's the purpose of this package?

Let me start with - why.

While developing my package, I am using TypeScript version v5.0.
The build compilation were failing because of the following error:

src/cli.ts(5,27): error TS7016: Could not find a declaration file for module 'lightningcss'. '/home/xeho91/Nextcloud/Projects/oss/typewind/node_modules/.pnpm/lightningcss@1.19.0/node_modules/
lightningcss/node/index.mjs' implicitly has an 'any' type.
  There are types at '/home/xeho91/Nextcloud/Projects/oss/typewind/packages/typewind/node_modules/lightningcss/node/index.d.ts', but this result could not be resolved when respecting package.
json "exports". The 'lightningcss' library may need to update its package.json or typings.

So, I cloned your reposiory, and I have used the tool publint, to see what's wrong.

There was a warning:

$ pnpm publint .
lightningcss lint results:
Warnings:
1. The library has types at node/index.d.ts but it is not exported from pkg.exports.
Consider adding it to pkg.exports.types to be compatible with TypeScript's "moduleResolution": "bundler" compiler option.

This is the reason of this Pull Request, a simple, one-line fix in package.json file.
