Add integration test for python 3.13 (#2381)
* Add integration test for python 3.13
* Check if we found any version of base image
* Fix test
* Use Registry Client to check for existence of base
* Make sure base image exists before declaring it
valid
* After resolving the name, make a call to the
registry to determine if it exists
* Create mock registry client
* Prevent the registry client from reaching out to
services during unit tests
* Remove test registry from unit tests
* Remove test_torch_1_13_0_base_image_fail
* This base image does not exist, so this test
was in error
