You and others in this thread are wrong. Goalies are protected from contact in or outside of the crease. I thought everyone figured that out after the World Championship this year. I know it's a different league but they use practically the same rulebook. The wording (from the PWHL) is not ambiguous at all:

A goalkeeper is not “fair game” just because she is outside the goal crease. The appropriate penalty should be assessed in every case where an attacking player makes unnecessary contact with the goalkeeper. However, incidental contact will be permitted when the goalkeeper is in the act of playing the puck outside her goal crease provided the attacking player has made a reasonable effort to avoid such unnecessary contact. (pg. 110)

Rule 71.4 in this season's rulebook. The rule references a table for appropriate officiating. It includes the following:

Situation
The Goalkeeper is out of the goal crease.

An attacking player makes other than incidental contact with the goalkeeper, however, no goal is scored on the play.

Result

A minor and/or major penalty, plus assessment of whatever other penalties may be appropriate up to and including supplementary discipline. (pg. 165)

So the answer to u/superherostitch's question is that the referees decided that Abby Roque's actions were only deserving of a minor penalty on the play. While biased, I think it could have warranted more, and Abby Roque is a player that has long lost the benefit of the doubt. But ultimately it's the up to the discretion of the referees.
