fix: Hide the xxx_sink variants from the public API

[rklaehn]

Description

These functions are internal and have no business being in the public API, I think

Breaking Changes

Removes

• api::remote::Remote::fetch_sink
• api::remote::Remote::execute_push_sink
• api::remote::Remote::execute_get_sink

Notes & open questions

Note: maybe we need to expose them at some point, but currently I don't see the need, and in any case the Sink trait is not exposed, so nobody can use them anyway at this time!

Change checklist

• Self-review.
• Documentation updates following the style guide, if relevant.
• Tests if relevant.
• All breaking changes documented.

They use a custom Sink trait, so yeah I think so too :)

Yeah, I needed something like a sink, but without all the poll madness of the one that is in futures...
