[Test] unit test help.test.ts is skipped now

[ananzh]

Describe the bug

Currently, help.test.ts test suite is skipped. To make a clean unit test, we want to explore and decide whether we still need to keep it as skipped.

/packages/osd-dev-utils/src/run/help.test.ts
Test Suites: 1 skipped, 0 of 1 total
Tests:       3 skipped, 3 total

To Reproduce
Run:yarn test:jest {path to help.test.ts}

Expected behavior
explore the skipped unit tests, check:

• can we enable all? if yes, create a PR and close the issue

• can we remove all? if yes, create a PR and close the issue

• should we keep all? if yes, describe the reasons in the issue.

The final output is expected to be a cleaned unit test with all the skipped ones being checked.
