Feat(json validation)

[revilowaldow]

This proof of concept feature adds live validation of the json schema within the renderer demo.
It further adds autocomplete suggestions similar to those available in VSCode.

It adds the new ace-linters lib and relies upon the language_tools extension for ace.

Things to consider:

• The language provider is created from CDN but could be implemented via a bundled web worker: https://github.com/mkslanc/ace-linters/wiki/Configuring-Ace-linters-with-JSON-language-service
• The schema is loaded from remote URL, but could be included in the site files instead. The canonical domain does not appear to have the node-modules folder available in the deployment.
• Performance does not seem ideal with larger content in the rendererdemo, and the initial state includes "__prop": "data" which is invalid.
• Validation could be provided in the convertor output editor when it is toggled from read-only mode, but this would need to be context aware of the active convertor to set the correct schema for the prop to be validated.
• There are further opportunities for inclusion of features such as snippets, like those in the popular VScode extension https://github.com/revilowaldow/5eTools-Language-Server/tree/main/snippets
• A minimum version of ace-linters of 1.5.1 is required due to Fails to resolve remote schema mkslanc/ace-linters#160

nifty stuff; any reason not to use the site-fast schema instead of site?

site-fast would IIRC only not bother validating adventure/book text.
As the renderer demo is just pure entries it wouldn't make any difference.
Note the schema points directly at entry.json rather than renderdemo.json as we're validating the contents of the data array rather than the file containing the data array

ah right enough, ty
