Update conda and pip requirements

[JDRomano2]

The conda environment.yml and pip setup.py files that specify prerequisites haven't been thoroughly tested or recently updated. We need to make it easy for any user to run the respective install commands and have it 'just work'.

A few contributing issues:

• numpy and Pandas version mismatches
• New syntax for creating and installing Conda environments
• Reliance on having a working mysql installation in order to install the python mysqlclient

Not all users will need to build the full comptox_ai database from scratch. Therefore, we can also remove the dependency on ista. Users who want to build it from scratch can install ista separately and deal with the database dependencies, etc. at that point in time.

To semi-future-proof this, we should create 2 GitHub actions - one that builds/installs ComptoxAI via conda, and one that does so for pip.

We want to build four GitHub Actions that does the following

1. Build the python package using pip and run pytest. It will say whether building fails or not. <- DONE
2. Build the documentation via Sphinx and test whether that completed successfully or not.
3. Deploy the website.
4. Deploy the python package to the Python Package Index (PyPI) whenever a Release is created in Github.
