Subject: [PATCH] build: remove quotes from rust-version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The script would include the quotes and so running `build/build` would
result in:

    $ build/build
    Running build..
    ✓ Radicle key already in ssh-agent
    Building Radicle 1.2.0..
    Creating archive of repository at e9cf91… in build/heartwood-e9cf91….tar.gz..
    Building image (radicle-build-1.2.0)..
    [1/2] STEP 1/17: FROM rust:"1.85"-alpine3.20 AS builder
    Error: creating build container: parsing reference "rust:\"1.85\"-alpine3.20": invalid reference format
