build: update dependency action to use carbon bot/app token

[matthewgallo]

Closes #6497

Uses same token approach as Core to open PRs so that it is opened by one of the Carbon github bots/apps. I also removed the slack integration piece since it doesn't work and wanted to do some cleanup.

What did you change?

.github/workflows/update.yml

How did you test and verify your work?

Haven't been able to yet! But the same APP_ID and APP_PRIVATE_KEY secrets have been added to our repo that are also used in core and those are used to generate the token used by peter-evans/create-pull-request.

Haha, I see you’re preparing to get yourself back into dependencies rotation. 😜

I think I consider dependencies more of a chore, although I guess based on the Angular conventions¹, build still seems appropriate. Maybe a good thing if we get more specific with our commit formats though than calling everything a chore. (I’m guilty of that too.)

Yes! I'm coming off the bench 😂 I went to add an approval to #6437 and realized that I couldn't since it was opened by me (my guess is that maybe I created the token that's currently passed to peter-evans/create-pull-request).

Both chore and build seem like valid options and I've seen both used across various different projects, happy to stick with build 👍

Haha, thanks for letting my air out my commit type thoughts. 😹 WELCOME BACK *to dependency land.
