Add support for aliases in ov

[sarayourfriend]

Problem

We tried adding aliases in #4343 using associative bash arrays. However, macOS's bash version is stuck on an older version that doesn't support associative arrays. So I removed that from the PR and decided to try it a different way in a future PR as a separate issue.

Description

Create some method of expanding aliases when running ov. For example, ov j should expand to ov just.

It should be possible with one-dimensional arrays, and treating odd-or-0 index as the alias and the following even index as the expansion. This would be preferred, as it's probably less overhead than something else (like the Python script).

Another option I thought of was to use Python to process argv in the entrypoint and expand the aliases there. The entrypoint could end with python ./docker/dev_env/expand_aliases.py "$@", and that script could import $OPENVERSE_PROJECT/.ov_aliases.py using a method like https://docs.python.org/3/library/importlib.html#importing-a-source-file-directly, and then do something like:

#... import personal_aliases from $OPENVERSE_PROJECT/.ov_aliases.py

shared_aliases = {
    "j": "just",
}

all_aliases = shared_aliases | personal_aliases

args = sys.argv[1:]
if args[0] in all_aliases:
  args[0] = all_aliases[args[0]]

sys.execv(args)

I've got the bash approach working pretty alright locally!
