`.bashrc` sync on GitHub with Jetson

[imzaynb]

There are a couple of environment variables that are set in the .bash_aliases file that is symlinked to the home directory of the jetson user on the Jetson. This seems dubious to me.

A .bash_aliases file, strictly, should be a file where different aliases are created to commands executed in the terminal, not anything else bash related.

A more fitting place for this to go is the .bashrc file. However, right now there is no .bashrc file that is symlinked to the home directory of the jetson. I think this makes sense, admittedly, because it is hard to say how this file might change depending on differing Ubuntu versions. However, I think there should be a file included in this repository that is sourced by the Jetson's .bashrc file which includes the declarations of the environment variables placed in the .bash_aliases file, and any other bash settings to set.

I noticed that there were a couple of added lines to the Jetson's .bashrc, which really should be documented somewhere on this repository.

This makes sense.

You can't symlink .basrc directly because it differs on ie. the base station, jetson, and docker setups.

For the few non-alias commands that we want to have on all platforms, the rationale for just put them in the bash_aliases is because it's already set up in all those places, but that can definitely be unexpected or potentially cause issues.
