Fix AddOrUpdateAnnotation recipe changing implicit value into explicit value in annotations with arrays

[jevanlingen]

What's changed?

When updating an existing annotation property, the recipe should not change implicit values.

What's your motivation?

The recipe creates uncompilable code when using an array with a implicit value.

For example:

@Foo({"oldTest"})
public class A {}

is turned into:

@Foo(value = "newTest1,newTest2", {"newTest1", "newTest2"})
public class A {}

where you would have expected:

@Foo({"newTest1", "newTest2"})
public class A {}

Checklist

• I've added unit tests to cover both positive and negative cases
• I've read and applied the recipe conventions and best practices
• I've used the IntelliJ IDEA auto-formatter on affected files
