refactor: 📦 Replace unmaintained unic-segment dependency

[berkus]

Fixes #978

[berkus]

@Keats if possible, this should be a non-breaking change. And will avoid the RUSTSEC hit for all downstreams.

[Keats]

looks like we need to bump the CI msrv

[berkus]

Can do.

@Keats wouldn't MSRV bump be breaking though?

[Keats]

No, it's basically impossible to keep a MSRV anyway

[berkus]

@Keats alright, bumped it, passes locally.

looks like the embark actions need some updates. I think they don't use Rust anymore, is there another one?

We use this here which if I understand correctly includes deny (and even zola as I just noticed :)

      - name: Install Cargo Tools
        uses: taiki-e/install-action@v2
        with:
          tool: cargo-deny

(Edit, you have to call cargo deny check then manually in a separate step)

[Keats]

looks like we can switch to that

[berkus]

Lets try this

@Keats could you please press the button?

[berkus]

Looks good!
