Add `skip_list` file in JiHu folder as for skip some Jest tests

Problem to solve

When we overwrite frontend components in jh, it may cause some unit tests to fail in our pipeline. So we wanna skip some ee or ce tests in the JiHu repo.

Proposal

Add skip list file in jh folder, indicates the path that needs to be skipped in the file.

{
  "fileList": [
    "spec/frontend/terms/components/app_spec.js"
  ]
}
