[SR-14135]Updating diagnostic message for convenience init in struct

[kaar3k]

struct Foo {
    let code: String

    convenience init(someCode: String) {    // error: delegating initializers in structs are not marked with 'convenience' 
        self.init(code: someCode)
    }

    init(code: String) {
        self.code = code
    }
}

Updating the above error message to initializers in structs are not marked with 'convenience'

• https://bugs.swift.org/browse/SR-14135
• There is already a fix it to remove the word convenience

New contributors can't immediately run CI since we had some abuse of that system in the past. In the meantime, you can ask someone else to do it for you.
