audience metadata component

✨ Feature

PR Description

This PR adds the "Target Audience" component for Doc Metadata:

• Added to the DocMetadata component
• Only renders if audiences metadata present in frontmatter with at least one valid audience key

Usage

Valid audience keys are defined in the component in a lookup dictionary. Currently they are:

• tre-operator
• federation-operator
• researcher
• integrator
• contributor
• everyone

These values go in YAML frontmatter as either a single string (for one audience only) or an array:

# string
audiences: tre-operator # valid single audience

# inline array example 1
audiences: [tre-operator] # valid single audience

# inline array example 2
audiences: [tre-operator, researcher]

# array example 1
audiences:
  - tre-operator # valid single audience

# array example 2
audiences:
  - tre-operator
  - researcher

# invalid keys - this metadata will render nothing
audiences: [treoperator, my-made-up-audience]

# invalid keys - this metadata will render only the valid key for Researcher
audiences: [researcher, my-made-up-audience]

If a page is open to everybody as readers/audience, what tag should I put?

do you think we should add everyone, or all as a key, so it renders "Everyone"? seems silly to list all of the audiences, for sure...
