feat: expand default custom link icons
## Details Request: #245 Adds support for several URLs out of the box in addition to default web: - youtube.com - github.com - neovim.io - stackoverflow.com - discord.com - reddit.com 2 other changes have been made to make configuring custom links easier: - The highlight gets pulled from the top level `link.highlight` option if a link specific one is not specified. This makes it so you don't need to copy `RenderMarkownLink` repeatedly while being backwards compatible and allowing users to override behavior. - When multiple patterns match a link we break ties by picking the longer pattern, idea being more specific pattern = longer pattern. However patterns can be long for other reason like the original default web pattern `^http[s]?://`, to make overriding this value more likely the pattern has been shortened to `^http`.
