Changed double to single quotes in the alias example so shells will interpret `$(pwd)` at alias runtime rather than load time.
For background on shell double vs. single quotes, see:

Bonus Thank You's:
1. SpaceVim is awesome and I tell everyone about it.
2. The SpaceVim image is my new favorite way to test issues I'm having on host SpaceVim, and it's always my host config's fault :P
This commit introduces a self contained Neovim build which runs
SpaceVim. This has multiple uses:
* Easy debugging environment. Quickly check if the problem is your
machine or really a bug in SpaceVim.
* Portability across machines as long as the destination has Docker
support.
