* Removed unnecessary 'global_step' from wandb logger. * Fixed wrong step implementation in wandb and missing metric skipping in logger base. * simplified metric check in base logger * Added Fix Description in CHANGELOG.md * Updated wandb logger tests. * udpate test, step=3 * Moved Fix Description in CHANGELOG.md to unreleased. * Update CHANGELOG.md Co-authored-by: Adrian Wälchli <aedu.waelchli@gmail.com> Co-authored-by: Jirka Borovec <Borda@users.noreply.github.com>
