Upgrade anyio[trio] version to above 4

[IterableTrucks]

anyio<4.0 will restrict the trio version under 0.22.0 which will cause conflict with loguru>=0.7.0 and emit the warning:

trio/_core/_multierror.py:511: RuntimeWarning: You seem to already have a custom sys.excepthook handler installed. I'll skip installing Trio's custom handler, but this means MultiErrors will not show full tracebacks.

The Python version is 3.9.18

Anyio is used by fastapi, we don't have to upgrade it, just following fastapi's anyio version

[IterableTrucks]

Fastapi requires Anyio indirectly by Starlette, and in the lastest version of Starlette the anyio version requirement is anyio>=3.4.0,<5. So there seems no reason to remain a tighter version constraint anyio = {version = "^3.6.2", extras = ["trio"]} which means anyio>=3.6.2,<4 in fastapi-login's dependencies.
