Docker: Fix YaCy version determination

The .dockerignore file was preventing the .git directory from being
copied into the context during container builds, which prevented ant
from determining the YaCy version by running a few git commands.

This fixes containerized YaCy peer's version showing up as:
yacy_v1.941_fatal: not a git repository (or any of the parent directories):
.gitfatal: not a git repository (or any of the parent directories):
.git_fatal: not a git repository (or any of the parent directories): .git
