Fix required maximum version of typing-extensions

[albertvillanova]

This PR fixes the required maximum version of typing-extensions.

Currently it is bounded to <4.2.0: typing_extensions>=3.7.4.1,<4.2.0; python_version < "3.8"

This PR sets the upper bound to all compatible versions, until the next major release <5.0.0.

Required:

• Fix required maximum version of typing-extensions confection#20

See:

• TypeError: dataclass_transform() got an unexpected keyword argument 'field_specifiers' spaCy#12034

See issue in pydantic:

• Pydantic 1.10.3 incompatible with typing-extensions 4.1.1 pydantic/pydantic#4885

See fixing PR in pydantic (typing-extensions>=4.2.0), which will be incompatible with your requirement typing_extensions>=3.7.4,<4.2.0; python_version < "3.8":

• Typing extensions min version pydantic/pydantic#4886

The failing CI tests should be fixed once

• Fix required maximum version of typing-extensions confection#20

merged and released.

Thanks for the PR and the context, we appreciate it!

As Pydantic 1.10.3 has been yanked, 1.10.2 should still work fine with spaCy and users shouldn't be impacted anymore. We'll talk internally whether we want to raise to <5.0.0 or perhaps something a little more restrictive like <4.5.0.

Putting in draft until confection is fixed.

We'll have to rerun the CI after the PyPI timeout issues are resolved.
