bug#62249: uniq -D long option name missing from man page

[Dan Jacobson]

man uniq has all the other long option names, except for -D's

       -d, --repeated
              only print duplicate lines, one for each group

       -D     print all duplicate lines

       --all-repeated[=METHOD]
              like  -D,  but  allow  separating  groups  with  an  empty line;
              METHOD={none(default),prepend,separate}

One needs to see (info "(coreutils) uniq invocation") to find it.
Please add it to the man page.
