Add support for "https://www.twitch.tv/directory/collection/<collectionname>" pages in Profile rules

[Taizunz]

Is your feature request related to a problem? Please describe.
I want to override profile settings for the Hype Train directory collection page, but that isn't currently possible as that isn't supported in the Profile rules->Current Page list.

Describe the solution you'd like
Add https://www.twitch.tv/directory/collection/<collectionname> as a supported option in the "Current Page"-setting in Profile rules.

Additional context
https://www.twitch.tv/directory/collection/hype-train
