Custom Nushell Builds

Build for Alpine, with (slightly) modified configuration based on default config.nu and env.nu.

Creates a Docker image containing:

• /usr/bin/ -> Nushell executable
• /root/.config/nushell/ -> Nushell configuration
• /root/.config/nushell/plugins/ -> Nushell plugins

Which means you can do this in a Dockerfile to install Nushell:

FROM ghcr.io/bfren/nushell:0.90.1 as nushell

FROM alpine as final
COPY --from=nushell / /
