Support bash before v4.4 #52

Closed gjkim42 closed 2 years ago

gjkim42 commented 2 years ago

Currently, kind-action does not work in an environment of having bash before 4.4(e.g. CentOS 7.9) with the following error.

... args[@]: unbound variable

This PR makes kind-action support bash before v4.4.
