Fix versions for dtype checks. Don't check v0.4

[will-moore]

My bad: For https://github.com/ome/ome-ngff-validator/pull/16#issuecomment-1297636546 the validator checks dtypes for v0.4 NGFF and asserts failure if dtypes mismatch (so that the PR could be tested). However, v0.4 NGFF with mismatching dtypes are not actually invalid. I forgot to revert that change before merging. So this PR fixes that and ONLY asserts that mismatching dtypes are invalid for versions after v0.4, to correspond to https://github.com/ome/ngff/pull/154

So, checking the mismatching dytpe sample from the PR above (v0.4) should no-longer give a warning: https://deploy-preview-18--ome-ngff-validator.netlify.app/?source=https://minio-dev.openmicroscopy.org/idr/v0.4/idr0077/9836832_z.zarr

Thanks, @will-moore. MSTM.

I assume it's considerably more work, but do you think it would be possible to get an informational message that this would cause an error/warning in the next version?

It will look like this with Error for versions 0.5+:

But for versions 0.1 - 0.4 you'll just see it as a warning:

Wow, nice!
