switch Readme version badge source to shields.io (#30411)

Summary:
Lately there are some loading issues for the `fury.io` badges service which results in missing image and alt text visible in the Readme.

This PR fixes that issue by switching to `shields.io` version badge - badge service that has been used for few other badges already.
