Bug: Build Of Alpine APK Packages Is Failing Due To A Dependency

[steelhead31]

Builds of the APK linux installer packages are failing, both using the new automated system, and if the previous static APK build files are used to produce a rebuild of the previous releases APK files.

FYI @gdams @sxa

I've done some investigating, the build of the package works ( both using the automated and old style builds ) if "Enable GPG Signing" is disabled, suggesting the issue in some way relates to the key/signing of the apk build.

[steelhead31]

disabling signing, all the packages build ok
signing with my own self signed cert and key works ok..

unpinning from alpine:3.21 fixes the build for JDK11+ ( it defaults to 3.19 ) but jdk8 is then broken

Fixed via #1120 & #1119
