wp-env: Allow Cache directory Via wp-env.json and .wp-env-override.json

[iamarunchaitanyajami]

Description

Allows users to override the cache directory when WP_ENV_HOME set in .wp-env.json and .wp-env-override.json.

How?

{
  "core": null,
  "plugins": [ "." ],
  "config": {
    "WP_ENV_HOME" : "/PATH/TO/YOUR/DIRECTORY"
  }
}

Testing

1. I used the WP_ENV_HOME variable locally in my .wp-env.json file and verified generated files were placed there.
2. I also checked that the default location and Environment Variable is still used if the environment variable is not specified.
3. I also tested that, if the container is running, the start command works successfully after deleting the wp-env home directory.

Thanks for this contribution @iamarunchaitanyajami!

Unfortunately, I don't think we should do this.

1. The config section only contains values for the wp-config.php file. Adding values to be consumed by wp-env itself could lead to conflicts.
2. WP_ENV_HOME allows users to change the cache directory on their own machine. These paths are specific to the filesystem and having them in a shared space like .wp-env.json seems like an accident waiting to happen.

Out of curiosity, could you share some context around your use-case for this feature?
