Allow for alternative authentication mechanisms for the Octokit object on construction.

[josephperrott]

Currently for the @actions/github this library extends @octokit/rest's Octokit class and in the super call assumes that the authentication is a standard token. (code link)

Other authentication methods should be valid here as well.

Looking at your linked PR, it looks like your use case is if you don't want to authenticate at all, right? I think I see a use case there, not sure if I see a use case for alternative auth methods - does that seem right?

[josephperrott]

The use case I specifically am running into is needing to authentication with a JWT.

I'm not sure whether we need to implement this.

The toolkit class is a thin wrapper convenience function for the common case GITHUB_TOKEN or PAT.

I could see the need if an input accepted a PAT or JWT and a function provided a single abstraction to do the right thing.

Otherwise I would recommend using the Octokit class directly.

Thoughts?

IMHO, @actions/github should not duplicate or wrap any of the features provided by @octokit/rest, but extend them. Therefore, authentication and all regular operations should be done with octokit. When a feature from @actions/github is required, it should accept an existing octokit object as an argument. It should not be required for @actions/github to handle authentication at all. For example:

const octokit = new Octokit(getInput('token', { required: false }))
const ghkit = new github.GitHub(octokit)

instead of https://github.com/eine/issue-runner/blob/258088daba8c0e57368d08b2afbc5795cf282490/ts/main.ts#L39-L45

Moreover, it seems that the only addition of https://github.com/actions/toolkit/tree/master/packages/github is that it provides the context for the current action. Wouldn't it be easier if it did just that, instead of being a passthrough for all octokit features?

fixed with #314 since the value of github.GitHub expanded to support runner proxy settings

now you can use a different auth mechanism, but still get the proxy settings.

@ericsciple can you remind me how to use different auth mechanism? I've read linked PR and dont really understand how it was meant to be achieved
