Update link to Piper download

[aaronsdevera]

Describe the bug
When running 01 locally, piper fails to download due to a bad url.

To Reproduce
Steps to reproduce the behavior:

1. on macOS, run poetry run 01 --local in the /software dir without piper model downloaded
2. See error

Expected behavior
01 is supposed to go and download piper via the defined URL:

PIPER_URL = "https://github.com/rhasspy/piper/releases/latest/download/"

However I am not aware if GitHub supports these types of URLs any longer. For instance, https://github.com/rhasspy/piper/releases/latest/ will redirect you to the page on GitHub for the latest release. Adding download to that URL will redirect to a GitHub 404.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• macOS
• python3.11

@aaronsdevera if you have the entire file name, not just to the latest folder, it will actually download it. I have tried it and got it working on my macOS using python3.11. The error is because of a ssl certificate validation problem. I am not sure what is wrong though. If I make it so the https request doesn't have to be verified (which you shouldn't do) in the tts.py, it works as intended.
