- Package translations in procps-lang.

I don't know why nls was disabled.
osc blame shows that `--disable-nls` is passed to configure script since at least 2012-06-04.
Didn't find a reason in changelog.
So let's try to package them and see what happens.

There are also man pages translations but they doesn't get installed automatically for some reason + it's probably already provided by manpages-l10n (https://salsa.debian.org/manpages-l10n-team/manpages-l10n/-/issues/6) so let's keep it that way. (forwarded request 868776 from 1Antoine1)
