Add Trellis docs for resolving local_path on Windows/ansible-local

Some genius wrote this:

The correct way to resolve this is to set your local_path in your wordpress_sites.yml file.

https://github.com/roots/trellis/blob/master/group_vars/production/wordpress_sites.yml#L11

I'm guessing that it's currently ../site, which is resolving to /vagrant/../site, which is /site, which doesn't exist. You should change that to something like /srv/www/example.com/current.

Alternatively, you can move your Vagrantfile one level up so that it sits alongside your trellis and site folders. This is how we used to do it in roots-example-project. Just make sure to change your ANSIBLE_PATH in Vagrantfile to something like File.join(__dir__, 'trellis') [ref]. This will put your site files in /vagrant/site and your trellis stuff in /vagrant/trellis. Now local_path: ../site will resolve to /vagrant/trellis/../site, which is /vagrant/site, which exists.

The latter suggestion of moving Vagrantfile up one level has the added benefit of making the settings work cross-platform.

@QWp6t @fullyint is this relevant anymore after recent Windows updates/docs?

Ref: #64

Yeah. In fact, I think roots/trellis#705 might have even made things worse in this regard insofar that there doesn't appear to be a cross-platform way to resolve local_path like there used to be. So this might need to be taken to the trellis repo since it could possibly be considered a regression.

Closing. Addressed in roots/trellis#725
