Investigate appropriate vendor string for Temurin builds

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();
```

https://github.com/adoptium/TKG/blob/master/src/org/openj9/envInfo/JavaInfo.java#L197-L198

-------

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

Start in src/org/openj9/envInfo/JavaInfo.java at the cited java.vendor handling around lines 171-174 and 197-198. Check the reported vendor value for each Temurin version produced, then determine which adoptopenjdk, eclipse, and temurin entries remain valid; done means the supported vendor handling and any historic entry are clearly identified and updated as needed.
