fix: upgrade toolkit-lib and use stack displayName

This upgrades toolkit-lib to the latest version which fixes the libCheck
typechecking. In the latest version toolkit-lib also updates the diff to
use the stack display name instead of the name/id so this updates the
action to also use the display name.
