OIDC support

[tacowan]

Is your feature request related to a problem? Please describe the problem.

I am trying to use Connect-MgGraph in github actions in a similar way to "az login". I would like to leverage OIDC similar to the approach used in "az login" see: https://github.com/Azure/login?tab=readme-ov-file#login-with-openid-connect-oidc-recommended

Describe the solution you'd like.

MgGraph would respect a federated identity credential ( example https://learn.microsoft.com/en-us/entra/workload-id/workload-identity-federation-create-trust?pivots=identity-wif-apps-methods-azp#github-actions) and perform the OIDC authorization flow when the clientid/application was configured for federation.

Additional context?
