feat: Make import.meta.glob and import.meta.globEager generic

[michaeloliverx]

This is my first PR so my apologies if I have done anything wrong.

Description

It would be useful if import.meta.glob and import.meta.globEager were generic functions. This change will allow users to do stuff like this:

import readingTime from "reading-time";

export type PostFrontmatter = {
  title?: string;
  description?: string;
  publishDate?: string;
  isPublished?: boolean;
};

type PostModule = {
  metadata: PostFrontmatter;
  default: { render: () => { html: string; css: string; head: string } };
};

const modules = import.meta.globEager<PostModule>("/content/blog/**/*.svx");
const postsMetadata = Object.entries(modules).map(([path, module]) => {
  // `module` is is now `PostModule` type
  const { metadata } = module;
  const { html } = module.default.render();
});

@patak-js seems we have flaky tests again 😭
The changes shouldn't have any effects on the failed tests, especially not for windows only 👀
