Release 2.5.1 (#271)

* feat: Support for custom authentication provider functions (#270)
* feat: Support for adding "draft" notes to the review, and publishing them, either individually or all at once. Addresses feature request #223.
* feat: Lets users select + checkout a merge request directly within Neovim, without exiting to the terminal
* fix: Checks that the remote feature branch exists and is up-to-date before creating a MR, starting a review, or opening the MR summary (#278)
* docs: We require some state from Diffview, this shows how to load that state prior to installing w/ Packer. Fixes #94.

This is a #MINOR release.
