Support for auto creation of type declaration file?

[Peeeaje]

print() has decent explanation when used as lsp. (Though the description seems to be wrong)

open() shows type information but doesn't show function exmplanation, and csv.reader() doesn't show anything.

I guess type declaration file has to be created in advance, the draft is created by program and if you want to add description you need to do that manually now. (These files are defined here: https://github.com/erg-lang/erg/tree/ca88e82c9f1186ddbfcd625d4bdb1f7dcc998ffb/crates/erg_compiler/lib/pystd)

If creating/updating them and fetching docs from original function realizes it would be pretty awesome.

It seems that pllyzer is creating type declaration file for my creating function, so doing the same for imported functions and fetching docs is needed for that?
