`roots/paths` filters missing from 3.x

[kapoko]

Version

3.x

What did you expect to happen?

Even though mentioned in the docs for 3.x the acorn/path filters do nothing in acorn 3.x

Relevant function in 2.x where the filters are still present: https://github.com/roots/acorn/blob/16b91ac15d17a861515552e958195b11e94b2a49/src/Roots/Acorn/Bootloader.php#L242-L259

Same function in 3.x: https://github.com/roots/acorn/blob/c94b27f83002ac12ef42790d1a4cfb270d512c61/src/Roots/Acorn/Bootloader.php#L324-L335

What actually happens?

add_filter('acorn/paths', ...) does nothing.

Steps to reproduce

In functions.php add the following filter before booting Acorn, it prints 'filter called' in Acorn 2.x but not in 3.x.

add_filter('acorn/paths', function() {
    var_dump('filter called');
});

\Roots\bootloader()->boot();

Thanks for bringing this to our attention.

We removed this feature in Acorn v3 in favor of environment variables or constants.

Feel free to define any of the following to override your paths:

• ACORN_BASEPATH
• ACORN_APP_PATH
• ACORN_CONFIG_PATH
• ACORN_STORAGE_PATH
• ACORN_RESOURCES_PATH
• ACORN_PUBLIC_PATH

Gonna punt this to the docs repo.

Thanks again!
