feat(io-ts-http): add patch http method type

We currently use api-ts in one of our internal services and we recently
came across a limitation wherein, we had the need to use the PATCH http
method but the api-ts service currently doesn't support it. As part of
PR, we're introducing the PATCH http method within api-ts.
