Configuration Properties AP no longer handles javadoc @value

[melix]

Issue description

I was working on updating the build plugins when, after upgrading a test to use latest Micronaut core, it started failing.

The test checks that we generate configuration properties adoc files correctly. It uses a class which has:

/**
     * Generic config default value is {@value GenericConfig#DEFAULT_VALUE}.
     *
     * @param config
     */

In Micronaut 3.9.7, it generates the following adoc file:

| `+generic.config+`
|int
|Generic config default value is {@value GenericConfig#DEFAULT_VALUE}.

However in 4.0.0, it misses the description from @value:

| `+normal.config+`
|int
|

I suspect this is related to an upgrade of Java Parser.
