SYS-607 update gitlab helm chart to 16.3.3; tweak ansible for virtualbox

[instantlinux]

Summary of Changes

Housekeeping update:

• Gitlab helm chart now supports version 16.3.3, which retired the logging_level setting for gitaly. (There is still 20x as much log output from gitlab container as there should be -- almost none of it useful -- and nobody at GitLab wants to tackle this problem after years of complaints.)
• Replaced deprecated apt_key resource with get_url in ansible fileserver role: I dunno why the folks at ansible didn't just fix apt_key to do the right thing for debian-based distros

Why is this change being made?

Support latest versions to comply with current security best practices.
