Update comment about needed Lua version in configure.ac (5.3 is needed, not 5.2)

Hello to the entire nmap community,
the comment in configure.ac:837 (Lua 5.2 needed) does not match
with the checks done (Lua 5.3 is actually needed!).

The following trivial patch attached in this email update that
comment.


Thank you!

Exactly Lua 5.3 is needed and checked, not 5.2.
