[MRG+2] Remove conda support

[aaronreidsmith]

Description

For the life of me, I cannot figure out conda. I have ended up in the following situations:

• Will build for 3.7 on all platforms (but not 3.6)
• Will build for 3.6 on all platforms (but not 3.7)
• Will build for only Linux, and nothing else

This PR removes all conda support (which, by definition, moves us off of Azure Pipelines entirely). The only thing it adds is a link from the GH badge to the GH Actions page, lol.

I will open an issue for first-party conda support and add a help-wanted tag, because it is impacting the release of features at this point.

Type of change

• Documentation change
• CI/CD Change

How Has This Been Tested?

pypi builds still work 🤷‍♂️

Checklist:

• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes

Thanks. We always have the Azure stuff stashed in past tags if we ever need to go back to it, but for now at least our build process is much more simple.

We can prob keep this here incase we ever go back to trying to automate this.

This was removed since this branch started as actually trying to commit meta.yaml. You're saying I should leave it in in case we go back to templating (à la #300) again?

[tgsmith61591]

Either way 🤷
