Attach the DataSharingTabHelper when versioning requires it

Even though shared tab groups might be disabled, we still want to
intercept some URLs when the app is out-of-date, to show a static page
when the feature is disabled by versioning, but no special UI is allowed
to show it. Instead, we open a static page.

For reference, this is equivalent to
https://source.chromium.org/chromium/chromium/src/+/main:chrome/browser/data_sharing/data_sharing_navigation_throttle.cc;l=57-58;drc=34f0d2690d43df1880f2cf7c265cf27d1c86e0a7
for the other platforms.

Tested: I tried to join a group from a link with the following flags:
- data-sharing: ON
- versioning: out-of-date, no UI.
It correctly opened the static page.
