i18n: install web.py and Babel globally

[scottbarnes]

Closes #8002

Fix

Technical

This adds a few packages globally to the local Docker development environment.

Obviously doubling packages is potentially pointless duplication, though it draws from the same source in requirements.txt and installs as few packages as possible.

This increases the size of site-packages on the development containers from 13 megabytes to 55 megabytes:

❯ docker compose run --rm -uroot home du -ch /usr/local/lib/python3.11/site-packages
...
55M total

Thoughts?

Before:

❯ docker compose run --rm -uroot home pip list

wheel      0.38.4    

After

❯ docker compose run --rm -uroot home pip list
WARN[0000] The "HOST" variable is not set. Defaulting to a blank string. 
Package          Version
---------------- -------
Babel            2.12.1
cheroot          10.0.0
jaraco.functools 3.9.0
more-itertools   10.1.0
pip              22.3.1
setuptools       65.5.1
web.py           0.62
wheel            0.38.4

That said, it does fix the issue:

❯ docker compose run --rm -uroot home ./scripts/i18n-messages update ja
WARN[0000] The "HOST" variable is not set. Defaulting to a blank string. 
Updating ['ja']
updated /openlibrary/openlibrary/i18n/ja/messages.po
compiled /openlibrary/openlibrary/i18n/ja/messages.po

Testing

docker compose build
docker compose run --rm -uroot home ./scripts/i18n-messages update <language code>

Nice! Not using looks like you already have pretty well :) I wish there was a way to handle this more smoothly, but this seems like a great interim fix!
