Theme check needs to verify settings values

Is your feature request related to a problem? Please describe.
Theme check for preset/default setting values and preset/default block setting values do not verify if the setting type is matched

Describe the solution you'd like
When we declare settings in the schema and provide a default value in the setting that doesn't match it's type it will throw an error (as expected). But when you try to do the same with settings within presets.[].settings, default.settings, presets.[].blocks.[].settings, or default.blocks.[].settings, it ignores the type.

Describe alternatives you've considered

• This might get more complicated if liquid variables are embedded or complex types are used (e.g. color), but seems like it's something that will make typing settings easier
