Improve Dependency Downloading in Dockerfile

[Aryamanraj]

Current Behavior:
Currently, the Dockerfile uses the following command to download dependencies:
RUN while read DEP; do wget -O $DEP; done < dependencies

Error:

[fs machine-core 6/6] RUN sha1sum -c shasumfile:
0.282 rom.bin: OK
0.282 sha1sum: can't open 'linux.bin': No such file or directory
0.293 linux.bin: FAILED
0.293 machine-emulator-tools.tar.gz: OK

This command expects each line in the dependencies file to be a URL. However, the -O option in wget is used to specify the local file name that the remote file should be saved as. Without specifying the remote file URL, this command could potentially fail or lead to unexpected behaviors.

Proposed Change:
Modify the dependency downloading command to accommodate a dependency file that contains both the file name and the URL. The suggested modification is:

RUN while read -r NAME URL; do wget -O "$NAME" "$URL"; done < dependencies

With this change, the dependencies file should contain pairs of file names and URLs, allowing each downloaded file to be saved with a specific name.
