chore(api): bump Python API version to 2.18 and tag new trash container methods (#14610)

# Overview

It's time for Python API version 2.18! Trash container `top()` methods
are the first features included in this version-in-progress.

# Test Plan

-
[sandbox](http://sandbox.docs.opentrons.com/papi-2.18-in-edge-time/v2/new_protocol_api.html#opentrons.protocol_api.TrashBin)
- automated tests

# Changelog

- bump max supported version
- decorate trash container top methods
- hide those methods from API reference, for now. they will be _shown_
in #14593 and the 2.18 docs feature branch.

# Review requests

sensible? correct? well-timed?

# Risk assessment

v low. this version bump was coming sooner or later and shouldn't affect
anything up through 2.17.
