Post type JSON files use not helpful labels

[felixarntz]

It looks like the export JSON files for content models / post types use the post meta field slug also as the field label, which seems like a bug - particularly since on the client-side the plugin already displays a nice human-readable "Name" value. It would make sense to me to use that same "Name" also for the post meta field label. See screenshot below:

That's a great point- especially as post meta labels might actually be in consideration for core: WordPress/gutenberg#65099
