Compile act cmd package with a built tag to grab gh cli auth and host info automatically

[ChristopherHX]

We could even detect a ghes authenticated by this package

https://pkg.go.dev/github.com/cli/go-gh/[email protected]/pkg/auth#TokenForHost

As of the current state of this project I'm only documenting it here

Expected outcome

we conditionally add gh cli interop code into the cmd package and adjust defaults and including the GITHUB_TOKEN secret and the github enterprise flags

[ChristopherHX]

Some of this stuff is done externally via scripts here: srz-zumix/gh-act

It's interesting to note gh extension search nektos does not even find this nektos act extension, but the older third party one....

To fix gh extension search nektos, the description field needs to be changed. I'd suggest:

-GitHub CLI Extension to run GitHub actions locally
+GitHub CLI Extension to run GitHub actions locally using nektos/act
