Deprecate tox in favor of running github actions locally via nektos act?

[anscfrisson]

📝 Description of the feature

nektos act is a tool to run github actions locally.

At least 3 ansys products mention nektos act in their README: https://github.com/search?q=org%3Aansys+nektos%2Fact&type=code

• https://github.com/ansys/pydynamicreporting
• https://github.com/ansys/pyensight
• https://github.com/ansys/pynexus

Should ansys-templates recommend netkos act instead of tox?

Benefits:

• developers can test github actions settings locally with more reproducible / intersectable configurations
• developers don't need to mirror and maintain settings for two environments (tox and github actions)

💡 Steps for implementing the feature

• Remove tox config
• Add nektos act setup in README
