Description

This PR removes the deprecated InstanceV1 endpoint and data class. With this change, we would only be able to support Mastodon 4.0+ which is very much in line with Mastodon’s supported versions which, as I’m writing this, look as follows:

Version	Supported
4.2.x	Yes
4.1.x	Yes
< 4.1	No

Closes #424

Easier review

Reviewing commit by commit will probably make the review process easier as I needed to remove code in multiple places and not all the changes were entirely related, but still relate to the general removal of the InstanceV1 endpoint.

Type of Change

Refactoring / cleanup
Documentation

Breaking Changes

The previously already marked deprecated call to GET /api/v1/instance has been removed. You can no longer get instance information for Mastodon server versions prior to Mastodon 4.0 which needed the v1 variant. Please use the v2 variant GET /api/v2/instance which is available via InstanceMethods#getInstance.
