Links to versioning examples are outdated

[zsrv]

Description

There are two links on the Setting up versioning page that point to an example site that uses versioning. These links point to https://squidfunk.github.io/mkdocs-material-example-versioning, which returns a "site not found" error.

Related links

• Setting up versioning

Proposed change

Change both links to point to https://mkdocs-material.github.io/example-versioning, which appears to be the new/correct link.
