Nginx 1.19.7+ Deprecated HTTP/2 variables

Updated Centmin Mod 123.09beta01 in preparation for some changes made into the next Nginx 1.19.7+ version to be released as outlined at Beta Branch - disable deprecated HTTP/2 variables in Nginx 1.19.7+ in 123.09beta01. Existing Centmin Mod 123.09beta01 or higher users can first run cmupdate to update local code and then run centmin.sh menu option 4 to recompile Nginx 1.19.7 to auto disable deprecated variables from nginx vhosts when Nginx 1.19.7 is eventually released.

Nginx 1.19.7 will deprecate HTTP/2 variables in nginx 1.19.7+ as per http://hg.nginx.org/nginx/rev/827202ca1269 and http://hg.nginx.org/nginx/rev/f790816a0e87 for http2_max_field_size, http2_max_header_size and http2_max_requests

If you're using these deprecated HTTP/2 variables in Nginx 1.19.7+ vhosts, on Nginx service restarts or Nginx config checks (nginx -t), you'll get Nginx warning messages as such but the Nginx service will still start and run Nginx server fine. Example warning message:
