Correct the Java reference in the F# tour interface comment

[Copilot]

The F# Tour article includes an object-programming snippet whose comment incorrectly implied that Java always requires a new type definition to implement an interface. This updates the comment so it no longer makes that claim.

• Snippet correction

  • Updated the ImplementingInterfaces comment in samples/snippets/fsharp/tour.fs
  • Removed the or Java clause from the comparison

• Wording cleanup

  • Adjusted punctuation in the sentence for clarity and style consistency

/// This is an object that implements IDisposable via an Object Expression
/// Unlike other languages, such as C#, a new type definition is not needed
/// to implement an interface.
