fix(cargo): preserve version range using Less Than Equal

[caspermeijn]

What are you trying to accomplish?

I added the Less Than Equal version range in #9828, but that doesn't respect the original precision of the version number. Fix that by using the normal update_version logic for such version ranges.

Anything you want to highlight for special attention from reviewers?

No, I reuse existing code

How will you know you've accomplished your goal?

I added a new test which reproduces my problem.
