fix(script-v2): Use nushell built-ins

[gmpinder]

Was running into an issue testing on an alpine image:

[04:28:22 g.i/b/c/test-build-chunked-oci:pr-662-43_linux_amd64_unchunked] => ============================ Start 'script' Module ============================
[04:28:22 g.i/b/c/test-build-chunked-oci:pr-662-43_linux_amd64_unchunked] => find: unrecognized: -execdir
[04:28:22 g.i/b/c/test-build-chunked-oci:pr-662-43_linux_amd64_unchunked] => BusyBox v1.37.0 (2025-12-16 14:19:28 UTC) multi-call binary.

This PR updates the code to use Nushell built-ins to keep similar functionality across distros.

Reverted, sorry

@fiftydinar Thank you for resolving it so fast!

I know what this change was missing. I'll have to make a new PR.
