[PATCH proxmox-i18n] fix formats in translations

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

Detected with `make check` using gettext 0.26.

Strings were fixed in place where the fix is obvious, e.g. {0} -> {n}.

Else if any of the variables in msgid_plural were missing:

- If msgstr[n] is not in english, instead of trying to guess the correct
  translation we set it to "" to be safe.

- If msgstr[n] is in english, it is set to "", this was likely probably
  a translator error and might need reviewing anyways.

In the case of Ukrainian and Russian the first plural form (msgstr[0])
applies when n=1,21,31,41,... so msgfmt will consider it an error if any
variable defined in msgid_plural are missing in msgstr[0].

Notes:
    The script used was
    
    ```perl
    use Locale::PO;
    
    foreach my $la (@ARGV) {
        my $file = "$la.po";
        my $dest = "$la.with-formats.po";
    
        my $po = Locale::PO->load_file_asarray($file, 'utf8');
    
        die "The file $file does no exist\n" if !scalar(@$po);
    
        sub is_formated {
            my ($entry,) = @_;
    
            if ($entry->{msgid} =~ /{[a-z0-9_]*}/) {
                return 1;
            } elsif ($entry->{msgid_plural} =~ /{[a-z0-9_]*}/) {
                return 1;
            }
    
            return 0;
        }
    
        # Filter out obsolete entries and process flags in one pass
        my @clean_po = grep {!$_->{obsolete}} @$po;
    
        foreach (@clean_po) {
            my $entry = $_;
    
            if ($entry->{obsolete}) {
                print "$entry->{msgid}\n";
                next;
            }
    
            if ($entry->has_flag('javascript-format')) {
                $entry->remove_flag('javascript-format');
            }
    
            if (!$entry->has_flag('rust-format') && is_formated($entry)) {
                $entry->add_flag('rust-format');
            }
        }
    
        Locale::PO->save_file_fromarray($dest, \@clean_po, 'utf8');
    }
    ```
    
    and the check was done with
    
    ```
    flatpak run --command=msgfmt --filesystem=home org.freedesktop.Platform//25.08 --check "$LA".with-formats.po
    ```
