Minor issues in [mdspan.sub.map.right]

[miscco]

There seems to be a copy & past error in [mdspan.sub.map.right.1.3]

otherwise, submdspan_mapping_result{layout_left​::​mapping(sub_ext), offset},

I am pretty sure this should read

otherwise, submdspan_mapping_result{layout_right​::​mapping(sub_ext), offset},

Also there is some misformatting in https://eel.is/c++draft/mdspan.sub#map.right-note-1

The second one is a cxxdraft-htmlgen issue, thanks for the report. In general, if you see something bad on eel.is/c++draft, it's a good idea to assume it's a cxxdraft-htmlgen problem (and report it as such) unless the PDF is also affected.

@jwakely , @mhoemmen Any opinion here? This feels like an obvious cut&paste issue to me, comparing to its sibling layout_left.

[timsong-cpp]

The incoming paper says layout_right so this seems like a misapplication in #6919.

@jensmaurer Oh, I think I missed this one! Let me take a look.

@jensmaurer This should definitely read layout_right.

In https://eel.is/c++draft/mdspan.sub#map.right-1.3.2 (both the normative text and the Note), _rank should instead be rank_.
