use consistent fqdn for moduletemplate and update outdated moduletemplate file

[ruanxin]

Atm, we still have tests use outdated fqdn for kyma-project.io/template-operator moduletemplate, which makes tests difficut to understand and maintain.

e.g:

1. in test:
   

   lifecycle-manager/tests/integration/controller/mandatorymodule/deletion/controller_test.go

   Line 42 in 158fa52

   WithArguments(kcpClient, shared.FQDN, "kyma-project.io/template-operator").

2. in outdated moduletemplate:
   

   lifecycle-manager/tests/moduletemplates/operator_v1beta2_moduletemplate_kcp-module.yaml

   Line 21 in 03a80f5

   name: kyma-project.io/template-operator

AC:

• replace outdated moduletemplate which use kyma-project.io/template-operator
  - operator_v1beta2_moduletemplate_kcp-module.yaml is used for generate moduletemplate for integeration tests, it should be replaced with moduletemplate_template_operator_v1_regular.yaml
  - operator_v1beta2_moduletemplate_kcp-module-cred-label.yaml is used for testing oci-registry-cred label, update it with new ocm component descriptor (requires a push to oci registry)
  - operator_v1beta2_moduletemplate_kcp-module_updated.yaml is used here, replace it with moduletemplate which is used for e2e test for update test.
  - operator_v1beta2_moduletemplate_ocm.software.v3alpha1.yaml is for testing ocm schema v3alpha1, use kyma cli generate a new version with correct fqdn (requires a push to oci registry)
  - push newly generated artefacts
• adjust tests which use kyma-project.io/template-operator, replace it with kyma-project.io/module/template-operator, define a const fqdn name for sharing the usage among tests.
