Fix for issue #1

Update to a recent version of pyscript.

This pull request includes several changes to the index.html file and the addition of a new main.py file and pyscript.toml configuration file. The changes focus on updating the PyScript integration and moving the Python code to an external file.

PyScript Integration Updates:

• Updated the PyScript CSS and script tags in index.html to use the latest release version.
• Replaced the inline PyScript code in index.html with a script tag that references an external Python file main.py.

Code Refactoring:

• Moved the Python code from index.html to a new main.py file, which includes functions for URL parameter handling, version checking, and event listeners.

Configuration:

• Added a new pyscript.toml configuration file to specify the project name, description, required packages, and files to fetch.
