changes to environment

[epassaro]

Description

• We agreed to pin Python minor version to have the same version in Linux and macOS independently of the conda dependency solving process. Currently it's 3.7 due to pyne holding back newer python releases #1537
• Removed unused sphinxcontrib-tikz extension, not activated in conf.py.
• Unpinned numba bugfix version. Do not pin the bugfix version unless it's really necessary.
• Moved Jupyter to Visualization section since it's required for the new viz module.
• Commented out pyside2 since Qt GUI is not used and soon to be deprecated. Also gave us problems recently, see Issue creating new TARDIS env (pyside2) #1608
• Add previously removed tardisnuclear dependencies in a separate section. I removed them in the past because weren't used in TARDIS code, in the future please use a different section for packages that are not required by tardis package!.

Motivation and context

Regular env update. Also we had some other related files to mantain: the conda-forge package (requires moving to new package template first) and the numba pipeline (maintained by @KevinCawley). There's no nice way to keep dependency tracking in a single file, so let's keep the tardis_env3.yml file as tidy as possible.

How has this been tested?

• Testing pipeline.
• Other.

Examples

Type of change

• Bug fix.
