Use copy number insteead of appending (Copy) to each duplicate

Is your feature request related to a problem? Please describe.

When copying a post multiple times, the string (Copy) is appended to the post title. I'd like to propose two improvements:

• When copying a copy, the string (Copy) is appended again, leading to a series of (Copy)(Copy)(Copy) in the post title. Screenshot:

• When copying again the original post, the string (Copy) is appended just once even if there's already a post with title {post title} (Copy). This makes difficult to immediately distinguish which post is which in the posts list. Screenshot:

Describe the solution you'd like

Maybe consider to use a string with the copy number e.g.: (Copy 1) and then (Copy 2) etc. instead of multiple (Copy) (Copy)

Why do you think this feature is something we should consider for the Yoast SEO plugins?

For better usability

Additional context

Start by reproducing repeated copies of a WordPress post in the duplicate-post plugin and trace the entry point that generates the copied title. Done means copied titles use distinct numbered suffixes such as (Copy 1) and (Copy 2), without accumulating repeated (Copy) strings.
