[jdk17u-dev] RFR: 8283017: GHA: Workflows break with update release versions

[Aleksey Shipilev]

Unclean backport to enable GHA workflows for update releases. This drops the 17u-specific hack (https://bugs.openjdk.java.net/browse/JDK-8276130) from GHA, and uses the handling code from mainline.

Additional testing:
 - [ ] GHA checks still pass (in progress)
