ci: enable maxperf for docker cargo builds

[somehowchris]

Motivation

There's a maxperf profile, so why not build release builds for like ghcr in that profile? build once, benefit many

Solution

Replace the --release with --profile maxperf in the Dockerfile

I would rather not since it takes significantly longer for little benefit. I think we also wanted to use foundryup for dockerfiles but I don't know if we have an issue for that cc @mattsse @grandizzy @zerosnacks
