Fix hardcoded wp-cli execution paths

Proposed Changes

• Fix wp-cli execution from terminal on Mac when the feature is enabled

In dev mode, when running npm start, wp-cli in wasm is loaded correctly in the terminal, because it takes the path of the dev Electron + the path of the project and it considers that as a single command. It seems it didn't work before either. It was introduced on #268
If we consider something important, we can create an issue to tackle it separately.

Testing Instructions

• Run npm run make && STUDIO_TERMINAL_WP_CLI=true open out/Studio-darwin-arm64/Studio.app/Contents/MacOS/Studio
• Observe Studio opens correctly
• Click on "terminal" in the overview page
• Run wp --version
• Observe it returns WP-CLI 2.11.0.

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

I think it makes sense to at least document the issue separately so that we are aware that it exists.

The changes look good to me 👍 Thanks for the fix!

There is a small typo in the command pm run make instead of npm run make in the testing steps.
