improve description of omero metadata

[giovp]

Currently, the omero metadata section in the specs could be a bit more descriptive, this is a small attempt.

This info was kindly summarized by @will-moore here: https://github.com/ome/ome-zarr-py/pull/261#issuecomment-1525658925

EDIT: while this PR is purely to improve documentation, might be related to potential relaxation of omero metadata as discussed in https://github.com/ome/ngff/issues/192

Thanks, @giovp! (https://ngff--191.org.readthedocs.build/latest/index.html#omero-md)

If no one else has any comments, I'll move to get this in.

Looks good.

Although we normally wouldn't make changes to a spec after release, this extra info could be added back to the v0.4 spec and might be useful?

But not a blocker!

[will-moore]

Also with https://github.com/ome/ngff/issues/192 proposed, this change in latest would be updated again before release, so it would be good to have this description in the v0.4 spec, where it won't change.

sorry for radio silence @will-moore @joshmoore , I have time now, shall I just add the info as optional as discussed in #192 ? I yes, I can then submit changes to IO in ome-zarr-py . Let me know!

[will-moore]

I would copy what you have now to the v0.4 spec - since it describes that spec and is worth having there. Then (probably in #192) update it in the in latest/index.bs according to the proposed changes there. Probably easiest to keep them as separate PRs since this one just documents current state, but #192 is a change. I don't expect that to take a whole lot longer but you never know!

[giovp]

done, added it to 0.4

Great, thanks!
