Update tests for beta/RC version handling

Updated the test expectations to match the new behavior where pre-release
versions (beta, RC, alpha) are installed with exact version specifiers
instead of installing the latest stable version.

Changes:
- Updated test name from 'without version' to 'with version' for pre-releases
- Updated expectation to include version: [email protected]
- Added test for beta versions: [email protected]
- Added test for alpha versions: [email protected]
- Added test for invalid version formats with warning message check

All 39 examples now pass.
