Man page generation feature is not documented anywhere

[bartekpacia]

One of the bullet points listing cli's features in README says: "man and markdown format documentation generation".

Where is this feature documented? I could not find it.

That is the v2 docs. v2 has the feature. Its probably not documented very well but its there

@bartekpacia In support of making the core library smaller and only using stdlib dependencies, we decided to move these capabilities out into urfave/cli-docs but, to your point, this relationship is not well-documented 😬. WDYT about making this issue a child-of/tracked-by #1891 ?

[bartekpacia]

Yeah, agreed 👍

btw I already updated v3 readme on master branch to reflect this
