REFACTOR: move the banner from the rust source to the standard library (#8406)
Related to: - #8311 - #8353 # Description with the new `$nu.startup-time` from #8353 and as mentionned in #8311, we are now able to fully move the `nushell` banner from the `rust` source base to the standard library. this PR - removes all the `rust` source code for the banner - rewrites a perfect clone of the banner to `std.nu`, called `std banner` - call `std banner` from `default_config.nu` # User-Facing Changes see the demo: https://asciinema.org/a/566521 - no config will show the banner (e.g. `cargo run --release -- --no-config-file`) - a custom config without the `if $env.config.show_banner` block and no call to `std banner` would never show the banner - a custom config with the block and `config.show_banner = true` will show the banner - a custom config with the block and `config.show_banner = false` will NOT show the banner # Tests + Formatting a new test line has been added to `tests.nu` to check the length of the `std banner` output. - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting ``` $nothing ``` --------- Co-authored-by: Darren Schroeder <343840+fdncred@users.noreply.github.com>
