Issue Description:

import Foundation
import SwiftUI

// `fields` parameter is correctly converted from array literal to Set<Field>
let _ :Date.ComponentsFormatStyle  = .components(style: .abbreviated, fields: [.minute])
//                                                                            ^^^^^^^^^
let range = Date.now ..< Date.now
#warning("`fields` do not compile from array literal")
range.formatted(.components(style: .abbreviated, fields: [.minute]))
//                                                       ^^^^^^^^^
// compile error:
// Cannot convert value of type '[Any]' to expected argument type 'Set<Date.ComponentsFormatStyle.Field>?'
// Reference to member 'minute' cannot be resolved without a contextual type

// fields: add explicit .init then compile, should not need to add .init()
range.formatted(.components(style: .abbreviated, fields: .init([.minute])))
//                                                       ^^^^^

// same problem with SwiftUI Text:
// this do not compile:
Text(range, format: .components(style: .abbreviated, fields: [.minute]))
// this is fine:
Text(range, format: .components(style: .abbreviated, fields: .init([.minute])))

// this do not compile:
Text("\(range, format: .components(style: .abbreviated, fields: [.minute]))")
// this is fine:
Text("\(range, format: .components(style: .abbreviated, fields: .init([.minute])))")

[typesanitizer]

The range.formatted example works on main, so maybe that fix should be cherry-picked to 5.5. The others don't work, and I even see odd diagnostics such as error: incorrect argument label in call (have ':format:', expected ':formatter:').
