manuals: Fix typos in -offset for .Bd and .Bl

The intended value is:
    -offset indent
If there's any typo such that the value doesn't match the pre-defined
strings, then the offset is the same width as the value.  So by chance,
"-offset -ident" ended up being a standard-width indent (since the
default indent is 6 chars, and "-ident" also has 6 chars), whereas
"-offset -indent" had a longer indent, and "-offset ident" had a shorter
one.
