✨ Making `EmailAddress` comparable alphabetically

[LVMVRQUXL]

📝 Description

Similarly to the NotBlankString type, we would like to make the EmailAddress type comparable alphabetically by inheriting the Comparable interface.

interface EmailAddress : Comparable<EmailAddress> {
    override fun compareTo(other: EmailAddress): Int
}

Here's an example of comparing two email addresses from Kotlin code:

val first = EmailAddress.create("first@kotools.org")
val second = EmailAddress.create("second@kotools.org")
println(first < second) // true

Here's an example of comparing two email addresses from Java code:

final EmailAddress first = EmailAddress.Companion.create("first@kotools.org");
final EmailAddress second = EmailAddress.Companion.create("second@kotools.org");
System.out.println(first < second); // true

✅ Checklist

• [ ] Make the type comparable, test its compareTo function on Kotlin and Java, update the public API binaries and the unreleased changelog.
• [ ] Close this issue as completed and update tracking ones if present.

We should precise the checklist before marking this issue as ready.

We should stabilize the EmailAddress type's representation before making it comparable alphabetically.
