4912/validation error when updating resources

[Dinika]

Fixes #4912

Adds error details in json

At the moment I've not implemented this second part or "icing on the cake" mentioned in the issue mostly because right now I only get the schema https://neuroshapes.org/dash/cellcompositionvolume?rev=122 as a substring of the value error.message returned by nexus. I'm not sure if it's a good idea to parse this string (using regexp) to find the second link that kinda looks like an href and try to resolve it. It sounds flaky to me to do that. I want to discuss if schema.contentUrl.@id can be used instead:

Icing on the cake, presenting a validation specific output that provides links to the relevant schema so the user can navigate to it without losing the vlaidation report currently on screen (e.g. opening a new tab).

How has this been tested?
