Update description in view.schema.json

[imagejan]

Fix formatting of html-like tags in description string.

I'm unsure how https://github.com/mobie/mobie.github.io/blob/master/specs/mobie_spec.md is generated from the content of the spec files like https://github.com/mobie/mobie.github.io/blob/master/schema/view.schema.json, but on https://mobie.github.io/specs/mobie_spec.html these fields are currently interpreted as HTML tags and therefore rendered wrongly.

I edited view.schema.json only, but the change will be required in the markdown file as well, I guess.

I am not sure here...

@constantinpape could you please have a look at this?

Thanks @imagejan. The markdown generation is done with this script:
https://github.com/mobie/mobie.github.io/blob/master/scripts/generate_spec_description.py

You can see if running this and committing the output works on your end, otherwise I can give it a try.

(And ideally the CI would take care of this, but I didn't have the time for that.)
