Tweak run-external signature so command must be a string (#8971)
Tiny fix: clarify in `run-external`'s signature that the external command must be a string. ### Before ``` Signatures: <any> | run-external <any> -> <any> Parameters: command <any>: external command to run ...args <any>: arguments for external command ``` ### After ``` Signatures: <any> | run-external <string> -> <any> Parameters: command <string>: external command to run ...args <any>: arguments for external command ``` ### Notes I was hoping to change more `any`s to more specific types, but alas I think we can only change `command` right now. The input can be any type and it gets rendered to a string before being passed to the external. The args can be any value type and they get converted to strings. The output can be either binary or a string.
