doc: add Make target to run phpDocumentor with Docker

This target provides a convenient way for running phpDocumentor without
cluttering the system's configuration with PHP extensions, nor the
Composer dependencies.

See:
- https://hub.docker.com/r/phpdoc/phpdoc/dockerfile
- https://github.com/phpDocumentor/phpDocumentor2#via-docker

An alternative is to download the PHAR and run it locally:
