[FEATURE] Add parameter to suppress timestamp in @Generated annotation

[anessi]

Why do we need this improvement?

In the generated classes a @Generated annotation is added with a date attribute that contains the time when the classes got generated.

It would be nice to have a parameter that allows to not add the date attribute.

The current approach makes totally sense when you generate the classes during the build and don't checking them in to your VCS. However, when checking-in the generated code, the date attribute causes a diff each time it is re-generated. The date is not needed because this is tracked in the VCS. We are checkin-in the code because we don't have the ability to call npm during the build.

How will this change help?

For people that check-in their generated code, removing the date attribute would only show the relevant changes in the VCS diff and not irrelevant time-stamp changes.

How could it be implemented/designed?

A parameter could be added and the templates updated, to allow to suppress the date field. See https://github.com/asyncapi/java-spring-template/blob/master/template/src/main/java/com/asyncapi/model/%24%24message%24%24.java#L17 for more details.
