feat(installer): Update docker-compose.yml with HTTPS/3 + QUIC support via traefik

[shleeable]

Context

Based on https://github.com/orgs/fosrl/discussions/363 - please test and verify this to build some confidence for the Pangolin team.

Hey, there is not specific reason this isn't implemented other than we haven't tested it and had time to add it. I don't see why would can't in the future! Thanks for the suggestion :) - @miloschwartz

but the good news is it's been stable on traefik's side for many releases now. So I doubt there will be a regression, if there is, we should speak with the traefik team.

Description

• Updates the port forwarding for the 443 UDP port to traefik
• Enabled the http3 traefik entrypoint

How to test?

• Cherrypick PR
• Restart the docker compose services
• Open your firewall ports (if required)
• Test your endpoints using tools. eg: https://http3check.net/?host=loops.plus
• Celebrate the easy win

Will review shortly, the only caveat at the moment is there is two traefik configs one if crowdsec is selected and without.

Might be best if we consolodate these into a single dynamic template, to ensure we don't miss either with wins like this.

LGTM. I think @LaurenceJJones is right but we can tackle that in the future.
