Add py-shiny-validate to shinylive

This may be more appropriate to file in py-shinylive.

It would be useful if shinylive included this package by default, so that you did not need to add it in requirements.txt.

Thanks for the suggestion! Generally speaking, the packages we include in shinylive are included to avoid compilation issues with pyodide or to ensure compatibility with the pyodide used by shinylive. There are a number of trade-offs that come with including a package in the shinylive assets (size of the bundled assets and ease of updating are two key issues), so on the balance we try not to include pure-Python packages in the bundle (beyond Shiny and it's direct dependencies).

Fair trade-off! I saw packages such as faicons included and suspected that these were quite similar, and that it may have just been forgotten. Feel free to close this issue.
