This is bumping the python versions bundled inside our binaries. For macOS and AppImage, from 3.9.10 to 3.9.11. For Android, from 3.8.12 to 3.8.13. Windows is left untouched as I am having issues with the wine build when using 3.9.11. (see https://github.com/spesmilo/electrum/pull/7721#issuecomment-1071901116 )
python-for-android local recipes
These folders are recipes (build scripts) for most of our direct and transitive dependencies for the Android app. python-for-android has recipes built-in for many packages but it also allows users to specify their "local" recipes. Local recipes have precedence over the built-in recipes.
The local recipes we have here are mostly just used to pin down specific versions and hashes for reproducibility. The hashes are updated manually.
