Consider having more than one git credentials tokens from the same SCM

Is your task related to a problem? Please describe

According to our current logic, we do not propagate more than one scm token with the same scm endpoint and user id: https://github.com/eclipse-che/che-server/blob/4f8a84cb1d4a9a8cd1b698a33457222078114e3c/infrastructures/infrastructure-factory/src/main/java/org/eclipse/che/api/factory/server/scm/kubernetes/KubernetesGitCredentialManager.java#L107-L108 This might cause a problem when user has an oauth token which might be limited in permissions and a Personal Access Token with full permissions. There is a possibility that the oauth token would be propagated to a workspace but not the PAT, so it might cause problems with some git remote operations due to the oauth token restrictions.

Describe the solution you'd like
