regression from https://github.com/spesmilo/electrum/commit/3afa2fcdf3cce609d8813bbdd7b5962214de5ec0
This had shown up on the CI [0] but we did not notice - there is too many random failures, too much noise :(

What changed, and why it matters
This is a straightforward build fix for the Linux AppImage packaging process. The Dockerfile was missing the system-wide `python3` package, which caused a build script to fail with a 'python3: No such file or directory' error. The commit adds `python3` back to the list of installed packages. It is a build regression fix, not a security vulnerability.
No security action required. Treat as a normal build/maintenance fix.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit modifies contrib/build-linux/appimage/Dockerfile to add python3 to the apt-get install package list. This resolves a build-time regression introduced by an earlier commit that removed or omitted the system-wide Python installation, causing scripts invoked via /usr/bin/env python3 to fail during the AppImage build. The issue manifested in CI but was previously missed due to noisy build failures.
