Add team_tags field for list of team members

As a follow-up to the discussion in gitlab-com/office-of-the-ceo/office-of-the-ceo-team#365 (comment 2344903400)

Modifies the relevant shortcodes so that when pulling team members based on departments from the team.yml, it also looks at team_tags.

Validation

In /handbook/engineering/development/fulfillment/provision/, team members list does not change even with the following modification:

  departments:
  - Sec & Monetization
  - Engineering Function
  - Development Department
  - Fulfillment Section
  - Fulfillment Sub-department
  team_tags:
  - Fulfillment:Provision Team
