The banner will now use three new `$env.config.color_config` settings:
- `banner_foreground`: The primary color of the banner text
- `banner_highlight1`: Used for the first set of highlights, e.g.,
`Nushell`, `nu`, `GitHub`, et. al
- `banner_highlight2`: Used for the second set of highlights, e.g.
`Discord`, `Documentation`, et. al.
If the settings above are not defined, `banner` continues to use the
default green/purple/foreground. However, two more lines use the
purple/highlight2 in order to give more separation and consistency to
the colorization.
# Description
The `(version).build_os` variable inherits from `shadow_rs` `BUILD_OS`
which points to the OS on which the binary was built but does not
reflect the target if it was cross-compiled. We cross-compile several of
the targets for our binary releases. Thus the info in the banner was
misleading.
# User-Facing Changes
By changing to `build_target` the target triple is shown instead.
This is slightly more verbose but should also allow disambiguation
between the `musl` and `glibc` builds.
# Tests + Formatting
(-)
`std/core` is always loaded by Nushell during startup, and the
commands in it are always available. As such, it's renamed
`std/prelude`.
`scope modules` and `view files` now show `prelude` in place of
`core`.
