Make the docroot customisable (to something other than 'web')

[Patabugen]

Description:

The library assumes that your WordPress installation is in a web/ folder in the same directory as the docker-compose, but doesn't mention this anywhere in the docs (and is different from Laravel which uses public/.

It would be useful to be able to customise this (without having to publish the config), and I think the docs should mention the requirement.

Solutions

I'm happy to have a go at both and submit a PR, but wanted to check if you had any opinions on how it should be done.

We could set an Environment variable something like WP_CLI_PATH which would be passed to any calls to wp (or we could use the wp server specific --docroot=

Or we could be more specific and specify the webroot path (though I'm not sure whether that'd ever be more useful than being able to set the root in general?).

Any thoughts?
