3.4.5 is a fairly minor update. Some bugs are fixed and jgit is updated.
3.4.5 release notes:

3.5.2 is a bigger update and important adds support for being able to
upgrade to 3.6.0 later. There is a new copy-approvals command that must
be run offline on 3.5.2 before upgrading to 3.6.0. This copies approvals
in the notedb in a way that 3.6.0 can handle them apparently. The
release notes indicate this may take some time to run. We don't need to
run it now though and instead need to make note of it when we prepare
for the 3.6.0 upgrade.

For now don't overthink things and instead just get up to date with our
images.
