Emily 9f9e277b60 treewide: remove now-redundant lib.mdDoc calls
These (and the `*MD` functions apart from `literalMD`) are now no-ops
in nixpkgs and serve no purpose other than to add additional noise and
potentially mislead people into thinking unmarked DocBook documentation
will still be accepted.

Note that if backporting changes including documentation to 23.05,
the `mdDoc` calls will need to be re-added.

To reproduce this commit, run:

    $ NIX_PATH=nixpkgs=flake:nixpkgs/e7e69199f0372364a6106a1e735f68604f4c5a25 \
      nix shell nixpkgs#coreutils \
      -c find . -name '*.nix' \
      -exec nix run -- github:emilazy/nix-doc-munge/98dadf1f77351c2ba5dcb709a2a171d655f15099 \

The value has the grammar `Key[|OtherKey]`.
The list of key names is found in the header file
{file}`X11/keysymdef.h` (remove the
`XK_` prefix). Note that due to limitations
of X11 shifted keys must be specified as a shift key
followed by the key to be pressed rather than the actual
name of the character. For example to generate "{" the
expression `Shift_L|bracketleft` could be
used (assuming that you have a key with "{" above "[").
You can also specify keys in decimal (prefix #), octal (#0),
or hexadecimal (#0x). They will be interpreted as keycodes
unless no corresponding key name is found.
