SwiftArgumentParser: Update to 1.8.2

Update Swift Argument Parser to use release 1.8.2 for `main`, `rebranch`
and `next` to support SE-0501: HTML Coverage report, and another
proposal, allow for deprecating package products, which is currently in
a pitch [1].

Relates to: swiftlang/swift-package-manager#9076
