Improve how avro and proto schemas are shown in the registry
Because we can't parse proto schemas as JSON the current approach to use a JSON viewer does not work very well. A proper editor that is capable of showing well formatted JSON as well as some syntax highlighting and formatting for proto schemas is desirable. Maybe the monaco editor as needed in https://github.com/cloudhut/kowl/issues/212 could help here as well
Can monaco handle .proto files on its own?
In other words: when using vscode, would I need to install an addon in order for it to have proper syntax highlighting for proto files?
We'll have to figure out if it is possible to have addons in embedded version of monaco.
