Link the Dotfile and Segment connector docs

Both now have a page on probo.com, so their provider cards in the Add
Source dialog carry a Documentation link. The slugs match the page
filenames, which is what keeps the link off a 404.

Google Analytics and Square stay unlinked: they are OAuth connectors and
no OAuth connector has a docs page yet, so there is nothing to point at.
