Use `typing.Annotated[...]` for the type-hints

[MicaelJarniac]

Before:

from uplink import Consumer, get, Path, Query


class GitHub(Consumer):
    """A Python Client for the GitHub API."""

    @get("users/{user}/repos")
    def get_repos(self, user: Path, sort_by: Query("sort")):
       """Get user's public repositories."""

After:

from typing import Annotated
from uplink import Consumer, get, Path, Query


class GitHub(Consumer):
    """A Python Client for the GitHub API."""

    @get("users/{user}/repos")
    def get_repos(self, user: Annotated[str, Path], sort_by: Annotated[str, Query("sort")]):
       """Get user's public repositories."""

This is similar to how Pydantic deals with fields:
https://docs.pydantic.dev/latest/concepts/fields/#the-annotated-pattern

from typing import Annotated

from pydantic import BaseModel, Field, WithJsonSchema


class Model(BaseModel):
    name: Annotated[str, Field(strict=True), WithJsonSchema({'extra': 'data'})]

I don't mean for the current method to be completely replaced by this, only for this new method to also be supported.
