Libs(ruby): expose patch endpoints

[maful]

Motivation

I've noticed that the patch endpoints, which were introduced back in v1.6.0, aren't currently exposed in the way they should be. This omission can lead to errors when users attempt to utilize these patch endpoints, particularly when building request bodies for endpoint resources. A case in point is the Svix::EndpointPatch error, which serves as an illustrative example of the underlying issue:

irb(main):001:0> Svix::EndpointPatch.new({})
(irb):1:in `<main>': uninitialized constant Svix::EndpointPatch (NameError)

Svix::EndpointPatch.new({})
    ^^^^^^^^^^^^^^^
Did you mean?  Svix::EndpointUpdate
               Svix::EndpointOut
               Svix::EndpointAPI

Solution

To address this issue, I propose to expose the patch endpoints within the ruby/lib/svix.rb file.
