Windows Playbook Java installation API broken

[HusainYusufali]

The Windows playbook roles that install the OpenJ9 Java doesn't work because it produces multiple zip files because of the new large heap binary. Adding heap_size variable to the URL should fix this.

"OpenJDK8U-jdk_x64_windows_openj9_8u222b10_openj9-0.15.1.zip", "heap_size": "normal"
"OpenJDK8U-jdk_x64_windows_openj9_windowsXL_8u222b10_openj9-0.15.1.zip", "heap_size": "large"

The affected roles are Java8, Java11, and Java12.

Not sure what the default should be, but it can be added to AdoptOpenJDK_Windows_Playbook/group_vars/all/adoptopenjdk_variables.yml.

We generally use the hotspot ones at AdoptOpenJDK so this isn't an issue, but we don't have any particular need for the large heap ones to my knowledge so I'd pick normal for any PR on this.
