False positive report of UnusedVariable for fields used with JUnit5 FieldSource annotation

[genericjon]

A variable that is used by JUnit5's FieldSource annotation will be flagged as an unused variable. The FieldSource annotation was introduced in JUnit version 5.11.

Example:

class FieldSourceTest {
    private static final List<String> fooParameters = List.of("apple", "banana");

    @ParameterizedTest
    @FieldSource("fooParameters")
    public void foo(String bar) {
        System.out.println(bar);
    }
}

Output:

FieldSourceTest.java:2: error: [UnusedVariable] The field 'fooParameters' is never read.

This is similar to #2335, where methods used by MethodSource were flagged as unused.
