Fmd 348 metadata spec

[murdo-moj]

• Added a page to display the metadata spec formed from the pydantic classes
• The page is dynamically created, but could be statically compiled as it won't change within a version.
• Missing at the moment is an indication as to which fields are filled in by the service user. There is not a concept of this in Pydantic. This can be left out of this page for now.
• The dataset registration page would make it clear which fields the user supplies.
• Loads of examples for Pydantic classes have been added. As Entity subclasses have different URNs I have overloaded the urn attribute on subclasses eg the Chart class to display a chart urn example.
• Something to consider: should fields with types that are classes eg Entity.Domain have examples or should the example be a link to the Domain class?
• Fixed a bug in get_table_details where urn isn't passed to Table()
• How can text wrapping on examples work better?

Regarding the text wrapping, I think you can solve it with some css changes:

1. add a max-width to the column so it doesn't expand indefinitely
2. apply overflow:auto to the table so it is allowed to scroll horizontally

(Let me know if you want a hand with this)
