Removing tokenEndpoint and authorizationEndpoint so they will be fetched by the Gateway API translator. This is used to verify that EG uses the CA from BackendTLSPolicy when connecting to the OIDC provider's well-known endpoint.

Using curl instead of nc to verify that keycload is ready. This change fixed some flaky OIDC tests.

It's used here:

Test: func(t *testing.T, suite *suite.ConformanceTestSuite) {
		t.Run("oidc provider represented by a BackendCluster", func(t *testing.T) {
			testOIDC(t, suite, "testdata/oidc-securitypolicy-backendcluster.yaml")

The creation of SecurityPolicy is now started after keycloak pod is ready, so EG can fetch the auth and token points from the keycloak's well-known endpoint.
