Skip JaCoCo coverage check for auto-generated beta SDK

This SDK is auto-generated and only contains integration tests (Sample*Test.java)
that require real Azure credentials. In CI/CD environments without credentials,
all tests are skipped resulting in 0% coverage.

Since the tests can only run in credential-rich environments, JaCoCo coverage
checks are skipped. The library code will be properly tested when credentials
are available in appropriate test environments.
