Add clock drift error messages to remaining 18 implementations

Browse source 
When timestamp auth fails (401 with timestamp in error), show helpful message:
- Error: Request timestamp expired (must be within 5 minutes of server time)
- Your computer's clock may have drifted.
- NTP sync commands for Linux/macOS/Windows

Updated: Un.cs, Un.java, un.clj, un.cob, un.erl, un.ex, un.f90, un.forth,
un.fs, un.hs, un.lisp, un.m, un.ml, un.pro, un.r, un.raku, un.scm, un.zig

All 42 implementations now have clock drift detection.
