Per the adjusted FFmpeg pinning advice, packages that work on the
default version should use the unversioned variants to ease the
migration to future versions and reduce the number of packages that
end up referencing old versions.
I have left HandBrake pinned as it builds a custom patched FFmpeg.
these changes were generated with nixq 0.0.2, by running
nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix
two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.
Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.
