Subject: refcard.tex: Obsolete explanation for C-u M-.

In section{Tags}, following line

\key{find next occurrence of tag}{C-u M-.}

exists.

This explanation is for `find-tag` function which is obsolete since 25.1.
Currently M-. is binded for `xref-find-definitions`, and C-u M-. doesn’t
`find next occurrence of tag`.

This may affect not only etc/refcards/refcard.tex but all other translated ones
(cs-refcard.tex, de-refcard.tex, fr-refcard.tex, pl-refcard.tex, pt-br-refcard.tex,
ru-refcard.tex and sk-refcard.tex).

So simply deleting the line may be easy to solve.
