gurobi: add v9.1.2 and extend python (#25064)

- add version 9.1.2
- set a license file
- set the license environment variable
- remove the download and license information out of the description so
  it does not show up in environment modules
- extend python and set python version constraints
- build gurobipy to be used in any compatible python, used for more
  extensive computations than the gurobi shell
- remove preexisting PYTHONPATH from gurobi.sh as the shell uses a
  built-in python, which will likely be different from "system" python
- add maintainer
