Use www.jpackage.org "java-X-temurin" naming convention for Adoptium RPM files

For consistency with other JDK vendor RPM file naming, Adoptium should use the

```
java--
```
naming convention designed by http://www.jpackage.org/.

For example, the current `CentOS 10` `java-21-openjdk` file is named:

```
java-21-openjdk-21.0.5.0.11-4.el10.x86_64.rpm
```

That way searches like:

```
dnf search java-21-\*
```

would display options like `java-21-openjdk` and `java-21-temurin` and related subpackages.
