update collect.sh to use chkentry -S -q -I .num.sh
add -v 5 debugging to sbin/update_reg.sh
Changed VERSION to "2.2.1 2025-11-17".
improve update_reg.sh debugging
The sbin/update_reg.sh tool will call sbin/who_extract.sh
with -v level when the level is > 0.
The sbin/who_email.awk is more robust on looking
for the initial "who" line.
The sbin/who_extract.sh when debug level is >= 5
will run the sbin/who_email.awk first with a -v debug=level value.

Updated bin/who_email.awk VERSION to "2.0.1 2025-11-17".
Updated sbin/who_extract.sh VERSION to "2.2.1 2025-11-17".
