This upgrade was tricky. First, it did not compile unless upgrading
biz.aQute.bnd to v7.0.0. After that, the build fails, complaining about class
versions:
```
/home/runner/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-api/2.23.0/10741ddf9effd8e04d568148c2948a22f3f4cc73/log4j-api-2.23.0.jar(/org/apache/logging/log4j/Level.class):
warning: Cannot find annotation method 'value()' in type 'BaselineIgnore': bad
class file:
/home/runner/.gradle/caches/modules-2/files-2.1/biz.aQute.bnd/biz.aQute.bnd.annotation/7.0.0/8ad279ebf0d04ea89c5ce4d934189d0d16bb6d50/biz.aQute.bnd.annotation-7.0.0.jar(/aQute/bnd/annotation/baseline/BaselineIgnore.class)
class file has wrong version 61.0, should be 55.0
```
I cannot see that Log4j have officially announced that they require Java 17,
although their release note page at
https://logging.apache.org/log4j/2.x/release-notes.html says for the 2.22.1
release: "**While maintaining compatibility with Java 8, the artifacts in this
release where generated using JDK 17, unlike version 2.22.0 that used JDK
11.**".
@uschindler Can you decode what they mean by this and whether this is likely
a bug in the 2.23.0 release or if we cannot upgrade since they require java17?
PS: We should start thinking about JDK bump for Solr on main to at least 17.
