Remove /ver/ segments from Web UI docs links

Backports #45474

The Support component is the only Web UI component that renders docs
links that include the `/ver/` path segment. This change removes the
`/ver/` path segment from these links so they point to the default
version of the docs. The user can use the version dropdown within the
docs site to adjust the version. This change does not alter UTM
parameters.

With this change, we only need to manage redirects in the default
version of the docs site. This makes it less likely that users will
encounter 404 errors. And since the docs site only displays the current
version and previous two versions, link targets with the `/ver/` segment
will 404 in EOL Teleport versions. This change also prevents that
scenario.
