Add `pydoc` command

The standard library has a module pydoc which can be used for generating and viewing documentation. I suggest a command such as [prefix] pydoc <NAME> which calls pydoc.doc with the given name to show instant documentation. I feel like this could be useful when referring to a certain method when helping someone - here’s an example with str.find:

>>> import io
>>> import pydoc
>>> out = io.StringIO()
>>> pydoc.doc('str.find', output=out)
>>> print(out.getvalue())
Python Library Documentation: method_descriptor in str

str.find = find(...)
    S.find(sub[, start[, end]]) -> int
    
    Return the lowest index in S where substring sub is found,
    such that sub is contained within S[start:end].  Optional
    arguments start and end are interpreted as in slice notation.
    
    Return -1 on failure.

for “bigger” documentation such as help(dict), this generates quite the long output. It might be a good idea to truncate this or put it into a “pageable embed” (with reactions to move around). Also, I’ve yet to figure out if it’s somehow possible to include a link to the official docs…

No, I think the versatility would serve us well - the command will be a lot more useful if we can expand it out that way.

And it’s a great idea to not pollute your environment with packages.

It’s not important that only installed modules work, we can add modules in high demand. The majority of questions asked in our guild can normally be answered with python built-in functions. I’d say pydocs is fine.
