 We can run Hugo on a virtual machine of GitHub Actions by this Hugo action. Hugo extended version and Hugo Modules are supported.

-From `v2.0.0`, this Hugo action migrated to a JavaScript action. We no longer build or pull a Hugo docker image. Thanks to this change, we can complete this action less than **2 sec**. (A docker base action was taking about 1 min or more execution time to build or pull.)
