Failure in TestXYPointQueries [LUCENE-9859]

It seems we are trying to create distance queries with radius = 0 which is not allowed.

Failure:

```java
FAILED: org.apache.lucene.search.TestXYDocValuesQueries.testSamePointManyTimes

Error Message:
java.lang.IllegalArgumentException: radius must be bigger than 0, got 0.0

Stack Trace:

Reproduce with:

Migrated from [LUCENE-9859](https://issues.apache.org/jira/browse/LUCENE-9859) by Ignacio Vera (@iverase)

Start by reproducing TestXYPointQueries.testSamePointManyTimes with the Gradle command provided. Read TestXYDocValuesQueries.newDistanceQuery, XYDocValuesField.newSlowDistanceQuery, XYCircle, and BaseXYPointTestCase.verifyRandomDistances to trace the zero-radius case. Done means the targeted test no longer fails with the radius validation exception.
