Add user level Docker socket to common paths

[bendrucker]

In v4.13.0, Docker for Mac stopped providing /var/run/docker.sock, resulting in act failing on macOS. By default, it listens on ~/.docker/run/docker.sock instead.

This was a breaking change in a non-major release and a rollback is planned:

docker/for-mac#6529 (comment)

This PR adds the new socket path to the bugReport output. Hopefully seeing that the user-level socket is available will help users set DOCKER_HOST rather than filing a report.

In the long run, it sounds like Docker wants people to move away from hardcoding a Docker host, default or otherwise, in their clients. docker context list will return the user's configured endpoints.

See #1411
