[Feature] New authentication mechanism is required to deploy application from a Helm Charts repository which homed in GHE

[m1n9o]

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

Hey gurus, I wonder is there any solution to configure GHE credentials for KubeVela so that it can deploy applications from a Helm Charts repository homed in a GHE(Github Enterprise) repo.
I can see Kubevela supports to configure username and password shown in the doc.

Actually, we dont use username and password to login to the GHE. We need MFA to log in the GHE.

Describe the solution you'd like

So I wonder if any solution which leverages maybe sth like SSH keys? Deploy keys? Personally, I prefer git+ssh way of working. Maybe you can refer to here.

Describe alternatives you've considered
