chore: remove bok-choy

[salman2013]

Description:

As the bok-choy has been deprecated openedx/public-engineering#13, we are removing its usage from the code in this PR.

Ticket : https://github.com/orgs/openedx/projects/55/views/1?pane=issue&itemId=43871891

We should also drop the dependency on selenium but then I think this is good to merge.

[feanil]

It doesn't look like anything else is using selenium either, so it's probably safe to remove that from test.in as well.

[salman2013]

@feanil should i remove the selenium under the scope of this PR? or create separate one?

[feanil]

I think we should remove selenium along with bok-choy if it's not being used independently of bok-choy.

[salman2013]

@feanil done.

Starting with tox 4.0 we need to specifically allow all scripts/tools to be used in the tox commands section.
In this specific case, we are directly mentioning the script which has not been specified in the allowlist_externals section for the version_check env.
To make it work with tox 4 (Tested on my end locally), we can simply replace the following line

{toxinidir}/edx_proctoring/scripts/version_check.py

with

python {toxinidir}/edx_proctoring/scripts/version_check.py
