This simply bumps the Tor version to 0.4.6.7, the latest recommended release of Tor.
I have tested this locally and have not observed any issues in building or running it after running `make update_tor_version` and then building the image.
If there is more involved in bumping versions, please let me know.
Thanks!
Now:
- `make build` will build the container with tor version set in `current_tor_version` and `current_torsock_version`
- `make update_tor_version` will update theses files
