[v3] Document type inference with import.meta.glob

[aboutsimon]

Describe the bug

When using import.meta.glob with vite v3, no generic type is provided anymore. The JS Doc provides you with this information, but it would have helped me to have it in the official docs easily available.

Also, is this not a breaking change for typescript users, strictly speaking?

Thanks for a great project.

no generic type is provided anymore.

I think it is partially still there. (the syntax has changed though)

import.meta.glob<Record<string, string>>('./*.txt') // v2
import.meta.glob<string>('./*.txt') // v3
