Update fast-glob references

[ArmandPhilippot]

Since withastro/astro#13299, Astro no longer uses fast-glob but tinyglobby. Referring to a Discord issue, it seems there is a difference at least in the output order. So we might encounter issues with glob patterns too...

We still have links to fast-glob in:

• guides/imports.mdx
• upgrade-to/v5

The second link is not an issue I think. However, the first one is in a section named Glob Patterns in Astro so this could be confusing since glob patterns in Astro no longer rely on fast-glob (and neither Vite's import.meta.glob).

The issue is... fast-glob docs is a bit more detailed than tinyglobby docs so there is no equivalent link. From my understanding, fast-glob uses micromatch under the hood while tinyglobby uses picomatch.

So, does the read more link could be replaced

• from: https://github.com/mrmlnc/fast-glob#pattern-syntax
• to: https://github.com/micromatch/picomatch#globbing-features

In my opinion, this could work but maybe I'm missing something.

This is a small issue... I could have make a PR but I'm not sure I'm not missing something here so a discussion felt more appropriate!

Edit: related to the Discord issue, explaining that users should order themselves the output of getCollection to have confidence on the output order could be helpful I think. Maybe in Querying collections.
