[ISSUE #4836] Fix Git submodules checkout failure in CI Build C task (#4743)

* checkout submodules

* remove possible redundant "check out git submodule"

* minor naming unification (inrelevant with PR subject)

* Not triggering C task for now

* Use the same version of actions/checkout as 'Build' task for 'License Check' task

* Revert change to avoid conflict

* Update a renamed label
