Release 0.4.1

One fix, reported from a Xiaomi on Android 16: the font weight control did
nothing. Both bundled faces carry a single variable axis, wght, and the app was
asking for two — a font with no italic axis may refuse the whole request rather
than the part it cannot honour, and on a platform that does, every weight drew
at Regular with no error to show for it. The same declaration had quietly broken
the heavier weights on Android 7.0 and 7.1 as well.

A patch release, not a minor one: nothing else changed.

README.md and releases/README.md were written by tools/update_release_docs.py
rather than by hand, which is what it is for — and ReleaseDocsTest now has
something real to check, since the version, the archived APK and the checksum
all moved together.

The 0.4.0 row also gets its real commit in place of HEAD.
