Env: No way to skip setting WP_ENVIRONMENT_TYPE

[dd32]

Description

When using wp-env, it's not possible to NOT set the WP_ENVIRONMENT_TYPE constant at all.

This is problematic when wp-env is being used as part of unit testing, which may require changing the environment type dynamically.

One can arbitrarily set the constant value through a config mapping, but one cannot remove it.

This is problematic for unit testing, as the value of the constant (valid or not) is used as-is within WordPress (See wp_get_environment_type() - which is another thing to discuss)

Step-by-step reproduction instructions

1. Create a .wp-env.json file similar to the below
2. See that the Constant is still defined (see below)

{
	"config": {
		"WP_ENVIRONMENT_TYPE": false
	}
}

(Note, I've also tried '""' and null)

Still defined:

$ grep TYPE `npm run wp-env install-path 2>/dev/null | tail -n1`/tests-WordPress/*config*.php
/Users/user/.wp-env/9ddecbd0abdc3019693b13c896f02591/tests-WordPress/phpunit-wp-config.php:define( 'WP_ENVIRONMENT_TYPE', false );
/Users/user/.wp-env/9ddecbd0abdc3019693b13c896f02591/tests-WordPress/wp-config.php:define( 'WP_ENVIRONMENT_TYPE', false );
