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:

aerc: `programs.aerc.enable` is set, but `...extraConfig.general.unsafe-accounts-conf` is set to false or unset.
This will prevent aerc from starting; see `unsafe-accounts-conf` in the man page aerc-config(5):
> By default, the file permissions of accounts.conf must be restrictive and only allow reading by the file owner (0600).
> Set this option to true to ignore this permission check. Use this with care as it may expose your credentials.
These permissions are not possible with home-manager, since the generated file is in the nix-store (permissions 0444).
Therefore, please set `programs.aerc.extraConfig.general.unsafe-accounts-conf = true`.
This option is safe; if `passwordCommand` is properly set, no credentials will be written to the nix store.
