[BUG] Javadoc warnings on builder methods

[Vynnytska]

Description:
When using lombok and add javadoc on field inside a class, warnings are thrown when generating javadoc, which depends on delombok task.

To Reproduce:
Create a class with Value and Builder lombok annotation. Add javadoc on fields inside it and override some builder methods. For example,

/**
 * Class used to store a unit of log.
 */
@Value
@Builder
public class Log {

    @NonNull
    private final Severity severity;
    /**
     * Should be specified.
     */
    private final String message;
    /**
     * Optional field. {@link Log.Category#UNCATEGORIZED} by default.
     */
    private final Category category;

    public static class LogBuilder {

        public LogBuilder message(@NonNull String pattern, Object... arguments) {

            message = MessageFormat.format(pattern.replace("'", "''"), arguments);
            if (!message.endsWith(".")) {
                message = message + ".";
            }
            return this;
        }

        public Log build() {
            if (category == null) {
                category = Category.UNCATEGORIZED;
            }
            return new Log(severity, message, category);
        }

    }

}

Then run ./gradlew javadoc.
Actual behaviour:

Task :javadoc
warning: no @return
public Category getCategory() {
^
warning: no @param for category
public LogBuilder category(final Category category) {
^
warning: no @return
public LogBuilder category(final Category category) {
^
3 warnings

if add java docs @param and @return to java docs on category field, only one warning will bet thrown:

Task :javadoc
warning: no @return
public LogBuilder category(final Category category) {
^

Expected behavior:
No warnings.

Version info (please complete the following information):

• Lombok since 1.18.6v
• java 11
• gradle 6.0.1

I have the same issue: "...warning: no @param for..." for the current last available lombok version.
Looks like @rzwitserloot 's commit 0b0656a only fixes issue related to @return
