The mess with regexes is hard to read and think about which is why it
had bugs with handling some Gradle formats.
It also lowers further the number of dependencies pulled from 785 to 744.
Changes:
- Added `gradle_parser.awk` script for getting dependencies from Gradle
- Changed the `deps.urls` file to contain full URLs to POMs
- Dropped the `deps.urls.old` part since `get_urls.sh` no longer exists
- Added `CLR` for learing line to `scripts/colors.sh`
- Wrote a new `nix/deps/gradle/README.md`
- Re-generated `nix/pkgs/go-maven-resolver/deps.nix`
