adds roles to deploy notifications and seperate discord notifications

[SilasPeters]

This PR aims to clarify what is being deployed, and decrease the noise given by the deploy notifications. This is made possible by:

• Adding the roles to the deploy start notification
• Utilizing a new discord hook for both staging and production: the deployments hook. For both staging and production, there will be the production/staging channel (current), and (production|staging)-deployments (new). People can mute what they want. This PR supports differentiating the two hooks.

The bitwarden secret containing the discord webhook has been updated to reflect both production and staging webhooks.

To satisfy the linter, I renamed the fallacious-rooster role to rooster.

Once merged, I will create two new channels and update the webhooks to point to the new deployments channels.

The merge-base changed after approval.
