Using Set as operation name causes compilation failures

[keynmol]

The quickest way to reproduce is with Scala CLI

test.smithy

$version: "2.0"

namespace hellosmithy4s.spec

use smithy4s.api#simpleRestJson

@simpleRestJson
service HelloService {
  version: "1.0.0",
  operations: [Set]
}

@http(method: "POST", uri: "/api/update/{key}", code: 204)
operation Set {
  input := {
    @httpLabel
    @required
    key: Key,

    value: Value
  }
}

string Key
integer Value

Workaround - renaming Set to Update fixes the issue.
