Ended up using expect-type to assert against {} type.
Happy to find an alternative solution if we prefer not to introduce expect-type.
If we find expect-type valuable, we could refactor tests to use it extensively.

Add support for a new
omitAdditionalPropertiesFromSchemaoption.When the option is
true,FromSchemawill ignore JSON schemaadditionalPropertiesvalues and always infer closed objects (omitting{ [x: string]: unknown; }index signature type).The option is disabled by default and no breaking changes are expected.
Implements: #219
