[PATCH v2 02/11] doc-diff: drop --cut-footer switch

[Felipe Contreras <felipe.contreras@gmail.com>]

From: Martin Ågren <martin.agren@gmail.com>

Now that our doc-diff convinces Asciidoctor to insert the exact same
formatted dummy date as AsciiDoc, we can drop the --cut-footer switch.
It has been useful to ignore this difference between the two tools, but
it's effectively a no-op now. Similar to when we repurposed this from
--cut-header-footer in 83b0b8953e ("doc-diff: replace
--cut-header-footer with --cut-footer", 2019-09-16), just drop it
without worrying about any kind of backwards compatibility or user-base.
