No interpreter found for Python 3.11

[magdesign]

Summary

Trying to build Servo on musl based Alpine Linux/PostmarketOS, aarch64.

./mach build --dev fails with:

error: No interpreter found for Python 3.11 in virtual environments, managed installations, or search path

so i tried to manually
uv python install 3.11

which fails with:
error: uv does not yet provide musl Python distributions. See https://github.com/astral-sh/uv/issues/6890 to track support

my python --version is 3.12.8

Would be nice to mention in build book that musl based linux systems are not supported yet.

Platform

postmarketaOS edge, aarch64

Version

uv 0.5.29

Python version

Python 3.12.8

The musl python builds are tracked in #6890, please raise problems with servo builds in their bug tracker.

Generally the workaround is just to install Python without uv (i.e., from the system package manager).
