wp-cli missing support for native mariadb cmds (-dump,-check,etc); current DEPRECATION notices

[pgnd]

on wp running with a local mariadb install

mariadb -V
	mariadb from 11.4.4-MariaDB, client 15.2 for Linux (x86_64) using readline 5.1

echo $PATH
	/usr/local/mariadb-lts/bin:...

which mariadb-dump mariadb-check mysqldump mysqlcheck
	/usr/local/mariadb-lts/bin/mariadb-dump
	/usr/local/mariadb-lts/bin/mariadb-check
	/usr/local/mariadb-lts/bin/mysqldump
	/usr/local/mariadb-lts/bin/mysqlcheck

running

wp-cli cli version
	WP-CLI 2.11.0

wp-cli core version
	6.6.1

exec

wp-cli db check
	/usr/bin/env: ‘mysqlcheck’: No such file or directory

wp-cli db export wpcli-db-dump.sql
	/usr/bin/env: ‘mysqldump’: No such file or directory
	/usr/bin/env: ‘mysqldump’: No such file or directory

easy tmp fix for default install

ln -sf /usr/local/mariadb-lts/bin/mysqldump /usr/local/bin/
ln -sf /usr/local/mariadb-lts/bin/mysqlcheck /usr/local/bin/

now

wp-cli db check
	mysqlcheck: Deprecated program name. It will be removed in a future release, use '/usr/local/mariadb-lts/bin/mariadb-check' instead
	test.wp_commentmeta               OK
	...
	Success: Database checked.

wp-cli db export wpcli-db-dump.sql
	mysqldump: Deprecated program name. It will be removed in a future release, use '/usr/local/mariadb-lts/bin/mariadb-dump' instead
	mysqldump: Deprecated program name. It will be removed in a future release, use '/usr/local/mariadb-lts/bin/mariadb-dump' instead

ls -al wpcli-db-dump.sql
	-rw-rw----+ 1 wwwrun www 1.7M Aug 17 14:29 wpcli-db-dump.sql

noted & fixed, e.g., @ drush proj

not urgent at all.
would be a convenient cleanup to support both native mariadb-* &/or mysql* cmds.
