[infra] Adds community contribution section to the changelog script

[michelengelen]

This will add a section below the highlights giving the community contributors a special shoutout. We can still work on providing a social shoutout as well, but this is a first step towards recognition of community contributions. 💪🏼

Running the changelog script will now add a section below the highlights that looks like this:

Nice improvement! 👍

[michelengelen]

@alelthomas quick review of the wording please?

[LukasTy]

Are you sure we need this? 🤔

By the way, WDYT about moving this to the top and replacing this existing somewhat pointless sentence:

We'd like to offer a big thanks to the ${authors.length} contributors who made this release possible. Here are some highlights ✨

I am trying to align this with the approach the core team is taking and since they are currently listing all contributors (but will apply this change to their repo as well) they want to keep all mentions. Right @mnajdova?

By the way, WDYT about moving this to the top and replacing this existing somewhat pointless sentence:

I thought about this as well. Might be worth a shot. We can always move it back if we think this looks odd or misplaced. 👍🏼

Perfect!
