feat(backend-role): adding list verbs on applications and appprojects for backend-role

[dlactin]

Added list permissions for the backend role. Currently testing this out in a sandbox environment and ran into permission issues.

@dlactin Tks for your contribution!

This is a bit strange because the backend doesn't need list to get the Argo CD Application. Have you applied this change you your sandbox and confirm it fixed the issue? If not, please provide the backend-rolebinding live state as I am suspecting about something else as well.
