Default Lua functions should not always be extracted

[luttje]

Unrelated to this, but I feel like nothing should be generated for these standard library functions which are already documented by LuaLS.

You get generics and a more in-depth description of them with LuaLS anyway.

Although I see that may be problematic for entries like https://wiki.facepunch.com/gmod/Global.pcall which do add onto the description with gmod-specific info.

Looking at how LuaLS suggests functions that exist in both docs I'm actually quite happy with how it works for this specific example:

(press the down arrow twice)

So all definitions are visible.

pcall works the same.

What are situations where this results in undesirable suggestions? Would love some input

It might work but why? Gmod's documentation of the standard Lua functions are objectively worse. I don't work with gmod anymore so unfortunately i couldn't give you a solid example anymore, but I definitely created this issue for a reason
