Force casting fails if TextState has an unexpected storage

[myihsan]

Description

swift-navigation/Sources/SwiftNavigation/TextState.swift

Line 608 in ddcd641

Array(Mirror(reflecting: children[0].value).children)[0].value as! (Any, Formatter?)

The force casting above fails if the TextState has an unexpected storage such as AttibutedString.

LocalizedStringKey conforms to Equatable but returns false for equivalent format strings. To account for this we reflect on it to extract and string-format its storage.

I have noticed this comment and understand that this workaround is required for LocalizedStringKey.
But LocalizedStringResource does not seem to require it, so I think supporting LocalizedStringResource might be another workaround.

Checklist

• I have determined whether this bug is also reproducible in a vanilla SwiftUI project.
• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue or discussion.

Expected behavior

No crash, no matter what the the storage is.

Actual behavior

Crash if the storage is not (Any, Formatter?).

Steps to reproduce

1. Create a TextState with AttibutedString: TextState("\(AttributedString())")
2. Trigger LocalizedStringKey.formatted(locale:tableName:bundle:comment:) by initial a String or check the equability
