When editing an existing draft (vs creating a new one), use "Save
changes" instead of "Save draft" in the save/discard prompts. This
provides clearer context to the user about what action they're taking.
Add isEditingDraft prop to DraftsButton and ComposerTopBar, and
update both prompts (in DraftsButton and Composer) with conditional
copy based on whether we're editing an existing draft.
