Kubeconfig: Use user provided ingress https port for token dialer

Current implementation have issue if user provided non default https
port because during token creation request goes from api server to auth
service which uses default https port and resulted following error for
user mode networking (there is no support for customize http/https route
for system mode networking)
```
INFO Adding crc-admin and crc-developer contexts to kubeconfig...
ERRO Cannot update kubeconfig: Head "https://oauth-openshift.apps-crc.testing": dial tcp 127.0.0.1:443: connect: connection refused
```

With this PR we are passing that https port info to `addContext`
function and use it for dialer where we update the port in case request
have `oauth-openshift` as part of address which resolve this issue.
```
