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.
