Describe the solution you'd like

EF Core 8.0 brings interesting improvements to the JSON support feature introduced in 7.0, but it is still too limited to be usable with OpenIddict. Most notably, while primitive collections are now supported, dictionaries are not. Yet, dictionaries are used in some entities, like the application entity for DisplayNames.
