[Themes] Fix Theme Push Execution when password flag is provided

[jamesmengo]

WHY are these changes introduced?

• https://github.com/Shopify/develop-advanced-edits/issues/186
• Fixes the command execution when executed from environments such as CI
• Certain environments use the Theme Access app) for authentication. Unfortunately, this app doesn't provide access to the bulk asset upload endpoint, which was causing nothing to get pushed (and errors to get swallowed)

WHAT is this pull request doing?

• Calls the legacy (ruby) implementation of the push command when the password flag is provided
  • This is a temporary solution to fix the push command and any CI consumers without needing to explicitly provide the --stable flag
  • This PR will be reverted once ThemeKit adds support for calling the Bulk Upload endpoint in the Asset API

How to test your changes?

1. Checkout Main
2. Install the theme access app
3. Generate a password
4. Call pnpm shopify theme push --password <PASSWORD>
5. Checkout this branch
6. Repeat step 4

The first execution should have resulted in an empty theme being pushed
The second execution should result in the files being uploaded properly

Post-release steps

• Patch release
