Textadept 12.0 alpha 3

Textadept 12.0 alpha 3 is released from https://github.com/orbitalquark/textadept/releases/tag/textadept_12.0_alpha_3

This release does not have as many changes as previous alphas, so this ought to be the last alpha before the beta series. The biggest changes are autodetection of light/dark modes for Linux and macOS and revamped API documentation for better readability.
