#481 replaced SourceKit placeholders (like `<#code#>`) by LSP snippets for code actions, which are used to represent SourceKit refactoring and diagnostic Fix-Its. But LSP snippets are only supported for code completion, not for code actions. This results in LSP snippets like ${1:code} being inserted into the editor. Instead of replacing SourceKit placeholders by LSP placeholders, we should just remove them altogether from the code action response. rdar://92447079 [#488]
