Jenkins warning about NODE_LABEL being undefined on build pipelines

[sxa]

From the logs (Note, this is not specific to this particular job but appears to be the case on many of them. Potentially a conflict between the use of the name NODE_LABEL and LABEL but needs to be investigted and resolved as it is generating quite a bit of noise in the logs and is probably indicative of an underlying bug:

WARNING hudson.model.ParametersAction#filter: Skipped parameter NODE_LABELas it is undefined onbuild-scripts/jobs/jdk8u/jdk8u-alpine-linux-x64-temurin. Set -Dhudson.model.ParametersAction.keepUndefinedParameters=trueto allow undefined parameters to be injected as environment variables or-Dhudson.model.ParametersAction.safeParameters=[comma-separated list]to whitelist specific parameter names, even though it represents a security breach or-Dhudson.model.ParametersAction.keepUndefinedParameters=false to no longer show this message.

I'm disinclined to set that parameter to mask a potential issue so we should look at driving a resolution.

(There are quite a lot of these in the test jobs too e.g. PLATFORM_AND_MACHINE, NON_AQA_TEST_REPOS etc. but they can potentially be covered under a separate issue)

Closing this to continue resolution under adoptium/infrastructure#2774 (comment)
