Repair wp/6.3 branch Actions: Pass debug step arguments through to wp-env - #83806

Part of #82930.

What?

Adds -- right after npm run wp-env in each command of unit-test.yml's "Docker container debug information" step, so npm passes the whole command through to wp-env unchanged.

Why?

Without it, npm treats the rest of the arguments as its own: it drops the -- separator and swallows short flags such as -m, -i and -a. None of the step's commands ran as written:

• mysql -- --version, php -- --version and phpunit -- --version reached wp-env as its own --version flag, so each printed the wp-env version.
• php -m and php -i ran as a bare php, and locale -a as a bare locale.

The step passed without logging any of the information it exists for.

Now that the commands really run, the mysql --version line fails: this branch's floating mariadb image is MariaDB 11.0 or later, which no longer includes the mysql alias for the mariadb client. The next PR in this stack, #83839, fixes that.

Upstream

trunk has used the same form (npm run wp-env-test -- run …) since #75341.
