Add doc how to show hidden (dot) files

[Natherul]

Is your feature related to a problem?

Yes, I cant find any documentation on how its done. Its been asked several times in git (in now closed issues) but even following those I cannot seem to be able to do this.

As example:
AstroNvim/AstroNvim#631
Contains code snippets that does nothing, or Im simply not understanding them.

Describe the new feature

Write clear documentation somewhere on https://astronvim.com/ with what file to edit and how to edit it. (with full file example would be best)

Additional context

No response

This can be found with ? in the neo-tree filetree or you can look at the neo-tree documentation. We are trying to minimize the duplicated documentation when the plugins themselves will have infinitely better documentation than we will write.

TL;DR H will toggle hidden files

[Natherul]

The TLDR does not apply. Im looking for a PERMANENT setting. I will however look at the documentation mentioned later.

EDIT: and purpose of not wanting double doc is fine but then it should be clear from your doc imho where to find this information as I was not aware of such when looking.

After more googling now that I know it was neo-tree I managed to solve it. For anyone stumbling across this.
