Investigate appropriate vendor string for Temurin builds

[smlambert]

There are several entries that represent Temurin builds in TKG code, check that they are valid and what implications there are of having multiples (adoptopenjdk, eclipse, temurin).

String vendor = System.getProperty("java.vendor");
String vendorLC = vendor.toLowerCase();

Check java.vendor for each version of Temurin we produce to verify validity. Likely need to keep adoptopenjdk as an historic entry.

I recall this issue now, the problem is that for JDK8 Temurin binaries, the java.vendor string in the build is "Temurin", (pulled from a JDK8 run from Grinder/12722

08:11:51  System.getProperty('java.vendor')=Temurin

but for JDK11+ Temurin binaries, the vendor is set as "Eclipse Adoptium", which means we are ignoring any test target exclusion that is intended for JDK8 and vendor "eclipse", (pulled from a JDK17 run from Grinder/12768

09:51:45  System.getProperty('java.vendor')=Eclipse Adoptium

Just a note, this could also affect the vendor exclusion strategy https://github.com/adoptium/aqa-tests/blob/master/openjdk/excludes/vendors/eclipse/ProblemList_openjdk8.txt.
