When you already have a `Version` in hand,
`normalize_version(version.text)` is a very roundabout way of calling
`version.to_string()`: it re-parses the version text to give you the
same `Version` you already had and then calls `to_string()` on that.

Then calling `escape_version()` on such a version is actually
counter-productive, per #6466.

Similar changes can and should be made over in poetry-core, but it
should be safe to merge this before that is done.
