feat!: enhance docs and doc command

changes the actual file format of docs
to markup since that's basically what we have been
using in the first place.

the docgen command has been modified to write
markdown headings with the function name and
yaml metadata for easy consumption by hugo for the
website (soon).

all other docs have been moved to markdown as well
this is the main reason this is a "breaking" change
users will have to reinstall hilbish
(task uninstall and task install) to remove the old
plaintext docs

+## Introduction
+Bait is the event emitter for Hilbish. Why name it bait? Why not.
+It throws hooks that you can catch. This is what you will use if
+you want to listen in on hooks to know when certain things have
+happened, like when you've changed directory, a command has failed,
+etc. To find all available hooks thrown by Hilbish, see doc hooks.
+
+## Functions
+### catch(name, cb)
+Catches a hook with `name`. Runs the `cb` when it is thrown
+
+### catchOnce(name, cb)
+Same as catch, but only runs the `cb` once and then removes the hook
+
+### hooks(name) -> {cb, cb...}
+Returns a table with hooks on the event with `name`.
+
+### release(name, catcher)
+Removes the `catcher` for the event with `name`
+For this to work, `catcher` has to be the same function used to catch
+an event, like one saved to a variable.
+
+### throw(name, ...args)
+Throws a hook with `name` with the provided `args`
