[Bug Report] Documentation: Environment pages were not generated.

[ppasupat]

Describe the bug The environment list https://farama-foundation.github.io/miniwob-plusplus/environments/list/ contains links that go nowhere.

From the GitHub Actions log, the "Build Envs Docs" step (docs/_scripts/gen_mds.py) has the following errors:

ID: miniwob/bisect-angle-v1
No module named 'miniwob.envs'
ID: miniwob/book-flight-v1
No module named 'miniwob.envs'
...

I couldn't reproduce this locally. On my local machine I was able to generate the environment pages. Probably a dependency issue.

Checklist

• [x] I have checked that there is no similar issue in the repo (required)

Looks like build-docs.yml has pip install . instead of pip install -e .

The Docker file for CI tests should also be updated.
