man: don't use versioned standard-options

man: don't use versioned standard-options

no-pager-255 was added in #29184, which I reviewed and agreed.
However, as #30887 came up, I reconsidered it a bit, and now
I actually think that this should be removed.

We add new tools that refer to these standard options. During
the process, some options are also promoted to be standard ones.
I think a more sane practice is to generally keep old tools in
the loop, rather than overloading the standard-options with versions.
