### What steps did you take and what happened? Provide a private github repo go getter url like this in the e2e config file: ``` - name: kubeadm type: BootstrapProvider versions: - name: v0.6.9 value: "git::ssh://git@git.myprivate.com/myorg/myrepo//capi-providers/bootstrap-talos/?timeout=120&ref=main" type: kustomize ``` Execute the e2e test and it results in the following error: ``` "failed to execute kustomize: Error: must build at directory: not a valid directory: evalsymlink failure on '/Users/me/src/repo/test/e2e/config/git::ssh://git@git.myprivate.com/myorg/myrepo//capi-providers/bootstrap-talos/?timeout=120&ref=main' : lstat /Users/me/src/repo/test/e2e/config/git::ssh:: no such file or directory\n", ``` The error is caused by this line: https://github.com/kubernetes-sigs/cluster-api/blob/main/test/framework/clusterctl/e2e_config.go#L514 version.value is not null and version.value is not url, further it checks if the version.value is an absolute path. Absolute path should start with '/' and in our case the go getter URL doesn't have that. So it appends the current e2e config file folder path to it, resulting in value '/Users/me/src/repo/test/e2e/config/git::ssh://git@git.myprivate.com/myorg/myrepo//capi-providers/bootstrap-talos/?timeout=120&ref=main' ### What did you expect to happen? The documentation says that it should support go getter url with kustomize type: https://github.com/kubernetes-sigs/cluster-api/blob/main/test/framework/clusterctl/e2e_config.go#L167 No error should be thrown and kustomize should successfully build using a go getter url value. ### Cluster API version v1.10.1 ### Kubernetes version v1.33.0 ### Anything else you would like to add? _No response_ ### Label(s) to be applied /area/e2e-testing
