Fix numpy v2 incompatibility (#536)

[Chessing234]

Summary

• Removes the numpy<2.0 upper bound constraint in pyproject.toml that was causing binary incompatibility errors (numpy.dtype size changed) with numpy v2
• The constraint was originally added while waiting for spacy and nmslib to support numpy v2; both now do (spacy >=3.7, nmslib >=2.1.2)
• Sets a minimum of numpy>=1.24.0 to ensure a reasonably modern numpy version

Fixes #536

Test plan

• Install scispacy with numpy v2 and verify no numpy.dtype size changed errors
• Run existing test suite to confirm no regressions

Not sure if im completely off track with this, but:

• i built scispacy locally with the removal of numpy constraint
• that allowed spacy 3.8
• when trying to run scispacy models of version 0.5.4 i had a "config type mismatch with spacy 3.8's stricter validation"
  • include_static_vectors = "True" should be a bool but is a string
