fix(provider): ensure ServerName and PortForwardNamespace are set on ClientOptions when port forwarding

[onematchfox]

Configuring the provider with port forwarding is currently broken in v6.1.0 due to changes introduced in argoproj/argo-cd#14605. That PR introduced the requirement to set both ServerName and PortForwardNamespace when making use of port forwarding.

At present, v6.1.0 will fail with the following error as we are not setting these values.

╷
│ Error: failed to create new API client
│ 
│   with argocd_repository.this,
│   on repository.tf line 1, in resource "argocd_repository" "this":
│    1: resource "argocd_repository" "this" {
│ 
│ cannot find pod with selector: [app.kubernetes.io/name=] - use the --{component}-name flag in this command or set the environmental variable (Refer to
│ https://argo-cd.readthedocs.io/en/stable/user-guide/environment-variables), to change the Argo CD component name in the CLI
╵

This PR ensures that we set both of these values.

When new version will upload ? Will it have new tag or save 6.1.0 ?

When new version will upload ?

Once this PR has been reviewed and merged and I have time to kick off a release build.

Will it have new tag or save 6.1.0 ?

It will be a new version - 6.1.1

@oboukili Any chance you can take a quick look at this? Unfortunately this is affecting quite a few people that want to upgrade to 6.1.0.
