feat: add support for 'hyphenated' format in the serde module

[FrenchDilettante]

Hi folks, this is my first PR against this project, so if I'm doing anything wrong, by all means please let me know and I'll update it 🙏

While using the serde feature, I noticed that it lacks support for the hyphenated format:

#[derive(Deserialize)]
struct Product {
    [serde(with = "uuid::serde::hyphenated")],
    id: Uuid,
    label: String,
}

Looking at the code, I found out that the format is supported by the library, just missing from the serde feature itself. There was an issue documenting that gap: #534

While I was at it, I also fixed a couple of typos in the doc strings (serailized / serialized).

Thanks for working on this @FrenchDilettante! This change looks good to me. The only issue I spotted in the docs is also present in all the other serde modules. It's not something you've introduced. Clearly we need to do some more work in this area of the codebase to clean it up 🙂

This module would have been originally missing because the default text format is hyphenated, but introducing a dedicated module for it makes sense because that module forces binary-based formats to still use hyphenated strings, and rejects non hyphenated formats.
