Relax spacy version constraint to fix installation failures

The spacy<3.8.0 upper bound forced pip to install spacy 3.7.x, which
depends on thinc<8.3.0 and numpy<2.0.0. This caused build failures
(thinc/blis compilation from source) and numpy 2.x incompatibility.

Newer spacy (3.8+) ships proper wheels for all platforms including
ARM64, resolving the original blis build issue the constraint was
added for.

Fixes #296
