todo.sr.ht version upgrade

I pushed this upgrade through in the hope that it would fix
https://todo.dominic-ricottone.com/~dricottone/huttese/4 .

Unfortunately, it did not. Nonetheless, the package is upgraded.

Updates from first deployment

git.sr.ht target was mangled.

py3-colour, builds.sr.ht, and py3-srht target versions had to be bumped
down. The first is due to a unit test error; the others are due to
unreleased versions that apparently upstream is keeping private.

Several APKBUILD files had to be updated for version numbers and
checksums. Notably, py3-pygments had to be bumped down a version. It
seems that an updated APKBUILD was pushed to the repo before an updated
apk was pushed to the mirror. I am choosing to follow the mirror as the
canonical target.

New build process

Packages can now be built with `make`. The targets are all based on the
files that are served in the official mirror.

Re-added two dependencies of todo.sr.ht that I has missed.
