Describe the bug
When upgrading from MessageKit 3.3.0 to MessageKit 4.0.0, on Xcode 13.4.1 (13F100) I get the following error:

Malformed input JSON: Plugin declared with buildToolcapability but doesn't conform toBuildToolPlugin protocol

To Reproduce

All I did was remove the MessageKit cocoapod dependency, then add the MessageKit SPM dependency. I have restarted Xcode, cleaned the build project, and am attempting to download Xcode 14 Beta 3 to see if that fixes anything.

Expected behavior
MessageKit should not fail the build.
