Add fasttext to README.md

[ai]

Some LanguageTool guides recommend adding fasttext to system and set fasttextModel/fasttextBinary settings.

Does it really useful?

Should we add a guide? Or maybe add at least fasttext binary to Docker image?

fasttext is now available in the Alpine edge branch. This means it will probably be available in the next stable release, and we will be able to directly install it with apk add fasttext.

Until then, we would have to build it from source, maybe using the alpine's APKBUILD.

The user would have to set the variables langtool_fasttextBinary=/usr/bin/fasttext and langtool_fasttextModel=/fasttext.bin, and mount the model as a volume with -v /path/to/model.bin:/fasttext.bin:ro.
