Add "find_help_pages" function to search for help pages

[SyntaxError2505]

I just copied the "find_files" function but made the directory be the file path of the documentation.

this is a good start, the one single problem is that it will reset the current index

I am happy to merge this in but I need to get back to this allowing ceratin "one-shot" created picker instance that is destroyed on close. I think this is valuable overall! Would you like to work on something like this

Also I think we should enforce modes to be { "Fuzzy" } by default becuase the directory is pretty small and fuzzy matching will just work better

[SyntaxError2505]

Okay. I will fix the style errors and get to figuring that picker out. By fuzzy, do you mfn that live_grep like mode where you search for content or is there a function to search for filename?

[dmtrKovalenko]

The mode for content search

[SyntaxError2505]

I got to a point where I am happy. It is just a hidden find_files call with opts being passed trough but the path being set to the doc directory. As a user, the only thing I could make better is hide the icons because every file inside is just text anyways.

[SyntaxError2505]

at this point it could also just be a keybind on user side
