Set RollForward Behavior to Patch (#424)

This is apparently a more desirable behavior for global.json, as it
allows servers running any version of Dotnet 8.0.1xx to automatically
switch to a newer version than the base. This update was apparently
required for DS14, NS14, and Syndicate Station to work properly, since
Linux servers can't actually run 8.0.100, and the earliest they can use
is 8.0.105(which is still a viable version).
