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

Checklist

• I have checked and made sure that the proposal adheres to this plugin's principles

Start by locating the theme-check validation entry point for schema settings and the preset/default settings paths named in the issue. Trace how preset settings, default settings, and nested block settings are checked, then verify that mismatched values are rejected in each context, including any relevant tests you find nearby.
