Describe the Bug

astro check is resolving dependencies from its own directory (and thus not accessing the user's project dependencies, in case the astro directory is an a virtual global store not under the project directory), but doesn't declare typescript and @astrojs/check as dependencies, so it can't find them.

It should resolve from the user's project directory instead, so it can find them, e.g. with
createRequire(pathToFileURL(join(root, 'package.json'))).resolve('@astrojs/check')

What's the expected result?

It finds typescript and @astrojs/check when installed in the user's project directory, even if the astro dependency directory is not a child of it
