Support ULID

[pbzweihander]

This PR adds support for ulid.

Seems otherwise good, just a test missing from schema_derive_test.rs for the ulid case.

Also perhaps the known format thingy could be bit refactored.

#[cfg(not(any(feature = "uuid", feature = "ulid")))]
{
  true
}
#[cfg(all(feature = "uuid", not(feature = "ulid")))]
{
  format != "Ulid"
}
#[cfg(all(feature = "ulid", not(feature = "uuid")))]
{
  format != "Uuid"
}

Can you help with the test? I'm not sure how to write one

utoipa/utoipa-gen/tests/schema_derive_test.rs

Lines 4707 to 4730 in 56b6326

	fn derive_struct_with_arc() {
	use std::sync::Arc;
	let greeting = api_doc! {
	struct Greeting {
	greeting: Arc<String>
	}
	};
	assert_json_eq!(
	greeting,
	json!({
	"properties": {
	"greeting": {
	"type": "string"
	},
	},
	"required": [
	"greeting"
	],
	"type": "object"
	})
	)
	}

Just like in above one but it it should test a type that has the Ulid type.

#[test]
#[cfg(feature = "ulid")]
fn test {
    #[derive(ToSchema)]
    struct Foo {
        value: Ulid,
    }
    
    // ... and so on the assertion
}

I added test. Thanks!
