Issue 126: deprecate style only, style description only, and document only workflows

[k-doering-NOAA]

Addresses #126. This PR:

• Removes the use_* functions for style only, style description only, and document only workflows
• Adds a warning to the reusable workflows that they will soon be defunct (removed).

Users of these reusable workflows should instead use the doc-and-style-r reusable workflow, which can be set up using ghactions4r::use_style_and_document()

I think a remaining step that I should take would be to post an issue on repositories that are using this workflow, as I'm not sure the warnings are visible enough:

@iantaylor-NOAA would you be able to review this within the next week? If not, I can see if @kellijohnson-NOAA or @Bai-Li-NOAA are available.

@iantaylor-NOAA thanks so much for getting to this so quickly.

good point about adding a date! I'll make it December (unless @Bai-Li-NOAA is ok with removing them while I'm out, and I can let her pick the date :) )

I'm planning on just deleting the reusable workflows, which should cause the github actions to fail

I'll leave this open until I've posted on the repos that are using the workflows and the deprecation date has been added.

@k-doering-NOAA, sounds good. December is fine. I just updated one of the repos by running ghactions4r::use_r_cmd_check(), ghactions4r::use_doc_and_style_r(), and deleting old files which only took about 2 minutes: https://github.com/pfmc-assessments/PEPtools/commit/10eddd1971d57c34229a88e1a4454cd89c164c57.

Those were the only remaining repos using these workflows.
