feat(workflow): add random hash generation for console password in test-legacy-upgrade (#513)

* feat(workflow): add random hash generation for console password in test-legacy-upgrade

- Added a step to generate a random hash for the console password using /dev/urandom.
- Updated the params.json creation to use the generated hash instead of a fixed secret.
- Ensured the hash is printed for debugging purposes.

* fix(workflow): correct hash generation syntax in test-legacy-upgrade

- Fixed the syntax for generating a random hash for the console password using /dev/urandom.
- Ensured proper escaping of special characters in the tr command.

* chore(workflow): remove push trigger from test-legacy-upgrade workflow

- Removed the push event trigger to streamline the workflow execution.
- The workflow will now only trigger on pull requests affecting .github/workflows/**/*
