After cloning and forking repo, does one still need to do git clone?

You jumped from the cloning instructions to the building instructions, 
which are given for a particular Linux development system. You need to 
adjust for Windows - see the doc/building.md file in the repo you cloned.

The wget is to download a boot JDK for the build to use. If you already 
have one installed then you don't need to download one. Also wget is a 
Linux utility not Windows.

If you are building mainline JDK then at this stage you need a JDK 22 
boot JDK.

HTH.
