Relax typing-extensions constraint

[hongquan]

Tried to upgrade pydantic or django-stubs in my projects and got this error:

Because no versions of pydantic match >2.8.2,<3.0.0
 and pydantic (2.8.2) depends on typing-extensions (>=4.12.2), pydantic (>=2.8.2,<3.0.0) requires typing-extensions (>=4.12.2).
And because pyngo (2.0.1) depends on typing-extensions (>=3.7.4,<4.10.0)
 and no versions of pyngo match >2.0.1,<3.0.0, pydantic (>=2.8.2,<3.0.0) is incompatible with pyngo (>=2.0.1,<3.0.0).
So, because kaon depends on both pyngo (^2.0.1) and pydantic (^2.8.2), version solving failed.

I found that at the latest revision in main branch, the version constraint is already lifted. Could you release a new version of pyngo?
