Issue:
OpenAPI Spec 3.0 validation should not require exclusiveMinimum to be a number
As specified in https://spec.openapis.org/oas/3.0/schema/latest.html the field `exclusiveMinimum` is a boolean. But while using the example code in `doc/openapi.md` and changing it to the 3.0 instances, the validation fails with an JsonSchemaException: exclusiveMinimum value is not a number at ExclusiveMinimumValidator.java:45

I used it like this:
```
  JsonSchemaFactory factory = JsonSchemaFactory.getInstance(SpecVersion.VersionFlag.V4,
    builder -> builder.metaSchema(OpenApi30.getInstance())
      .defaultMetaSchemaIri(OpenApi30.getInstance().getIri()));

   jsonSchema =
    factory.getSchema(
      SchemaLocation.of("classpath:" + filePath + "#/components/schemas/" + schemaName));
```
and also tried VersionFlag.V7 and other variants. 

Expected behavior: 
```
 "value": {
    "minimum": 0,
    "exclusiveMinimum": true,
```
should validate just fine, with OpenAPI 3.0 and draft 4.

Note: in OpenAPI 3.1 this is changed to a number.
