chore: Update to the latest annotate-snippets

[Muscraft]

This PR updates annotate-snippets to the latest version and updates the adapter code¹ so that AnnotateSnippetEmitter's output matches HumanEmitter's output. If anyone would like to see the differences² between AnnotateSnippetEmitter and HumanEmitter, I have a branch where AnnotateSnippetEmitter is used in place of HumanEmitter.

Footnotes

1. A lot of the adapter code changes are based on code for HumanEmitter. ↩

2. Some of the test differences will go away when fix: Don't add diff symbol to unchanged lines #148001 and fix: Only special case single line item attribute suggestions #148004 are merged. ↩
