• All tests passed. If this feature is not already covered by the tests, I added new tests.
• This pull request is on the dev branch.
• I used npm run format for formatting the code before submitting the pull request.

Resolve collisions and enhance test performance by implementing the following actions:

1. Combine the Docker and Distribution tests into a single suite called "Cloud Instance Tests" to ensure there are no conflicts between them, such as:

   JFrog Artifactory Extension Tests
    1) "before all" hook in "JFrog Artifactory Extension Tests"


  0 passing (7s)
  1 failing

  1) JFrog Artifactory Extension Tests
       "before all" hook in "JFrog Artifactory Extension Tests":
     Error: Server responded to ***/artifactory/api/repositories/ado-extension-test-repo1-1730906673 with status code 400:
{
  "errors" : [ {
    "status" : 400,
    "message" : "Fail to create. Reason local repository with key: ado-extension-test-repo1-1730906673 already exist\n"
  } ]
}

2. Configure the Docker repository names to be timestamp-dependent, similar to other package types. This reduces the risk of collisions between different CI runs.
3. Avoid creating unnecessary repositories when certain tests are excluded.
