WICKET-7090: add outputTimestamp property to enable reproducible builds

In addition to reprocible builds, this should also result in timestamps
being set on files in jars.

>             Project: Wicket
>          Issue Type: Bug
>          Components: release
>    Affects Versions: 9.8.0, 9.9.0, 9.10.0, 9.11.0, 9.12.0, 9.13.0, 9.14.0, 9.15.0, 9.16.0
>            Reporter: Emond Papegaaij
>            Priority: Minor

> Starting with 9.8.0, the release jars are built with file entries without a last modification timestamp. This can cause issues if {{LastModifiedResourceVersion}} used for the {{{}resourceCachingStrategy{}}}. The browser may be using an older version of the resource, even if a newer version is available. This strategy is normally only used in development mode, but even then this can cause unexpected behavior.
> As discussed on the dev list, the best we can do is to set the last modification timestamp to fixed time during the release, as git doesn't track this. A suggestion is to use  the project.build.outputTimestamp property: https://maven.apache.org/guides/mini/guide-reproducible-builds.html
