update centmin.sh menu option 21 routines in 131.00stable

- update centmin.sh menu option 21 routine for generated restore-instructions.txt text
- update centmin.sh menu option 21 backup generated restore.sh script when you select centmin.sh menu option 21 submenu option 3 for Migrate Centmin Mod Data To New Centmin Mod Server option and you select mysqldump method instead of mariabackup method for MariaDB Mysql data backups. The restore.sh script needed a fix for individual database name restore command options in restore.sh that is generated
- update centmin.sh menu option 21 submenu option 1 option 3 for creating new SSH key for remote host. Previously, when it comes time to transfer the new generated SSH key's public key file to the remote host via ssh-copy-id, if the ssh-copy-id process fails, the routine will automatically remove the generated SSH key pairs' private and public key files. This update will improve the routine so that on ssh-copy-id failed transfer, prior to removing the SSH key pairs private and public key files, it will show the contents of both private and public key files. This can save time if you had a temp remote SSH server issue or restriction i.e. firewall or root user SSH restriction on remote host, and you do not want to re-run centmin.sh menu option 21 submenu option 1's option 3 again as you can use the displayed contents to manually recreate the SSH private and public key file contents.
