pio-package: add page

For #5517

[bl-ue]

See my suggestions. The valid extensions are .tar.gz and .zip; I picked .tar.gz because it's more Unix oriented and is traditionally what's meant by 'tarball'. I think it's good to have extensions on the tarball paths though because it makes it clear that they're to be files and not folders.

Also, I removed 'package' from 'current package directory' because that looks just a tad bit odd to me, and I think it conveys the same meaning without it; however, you can ignore that change if you want to.

Actually I think that you can either specify a file or a directory.

pio package publish [<source directory, tar.gz or zip>] [OPTIONS]

Oh, I didn't notice that message. Well, I doubt that it matters to document that...but idk.

I'd say that's what the More information link is for.
