Issue:
[Bug] IRI References with URL encoded '[' and ']' incorrectly fail validation
IRIs containing %-encoded `[` and `]` characters incorrectly fail validation due to the following code in the `IriFormat` and `IriReference` introduced in #983:

https://github.com/networknt/json-schema-validator/blob/772832511a9c495ebe6c9ec8908e5505da815e73/src/main/java/com/networknt/schema/format/IriReferenceFormat.java#L17-L23

`uri.getQuery()` decodes the query string, so this scenario fails validation even though `[` and `]` were correctly escaped. Potentially could use `uri.getRawQuery()` instead. This wasn't picked up in the original PR as there was no test case written that would pass when these characters were escaped, only that they were disallowed.

Additional test case that demonstrates the issue:

```
@Test
void queryWithEncodedBracketsShouldPass() {
    String schemaData = "{\r\n"
            + "  \"format\": \"iri-reference\"\r\n"
            + "}";

    SchemaValidatorsConfig config = new SchemaValidatorsConfig();
    config.setFormatAssertionsEnabled(true);
    JsonSchema schema = JsonSchemaFactory.getInstance(VersionFlag.V202012).getSchema(schemaData, config);
    Set<ValidationMessage> messages = schema.validate("\"https://test.com/assets/product.pdf?filter%5Btest%5D=1\"",
            InputFormat.JSON);
    assertTrue(messages.isEmpty()); // Fails
}
```
