chore: enable rust codepath on CI (#6449)

### Description

This PR switches to use the Rust codepath for turborepo CI.

Part of this PR switches our Windows usage to use GitBash instead of
Powershell for invoking `turbo`. This isn't ideal, but it allows us to
start dogfooding.

### Testing Instructions

Our existing CI should pass. We should eagerly revert if an issue is
discovered.

Closes TURBO-1665
