Bug 33402: Move ERM Cypress tests to their own directory

We need to move the existing Cypress tests (that are ERM only, t/cypress/integration/*.ts )
to their own subdirectory, eg t/cypress/integration/ERM

Test plan:
Confirm that the cypress tests are still passing after this change:
  perl /kohadevbox/misc4dev/run_tests.pl --run-cypress-tests-only
