typing_extensions.Buffer requires `typing-extensions>=4.6`

Things to check first

• [X] I have searched the existing issues and didn't find my bug already reported there

• [X] I have checked that my bug is still present in the latest release

Typeguard version

4.2.1

Python version

3.10.12

What happened?

typeguard uses typing_extensions.Buffer, which was only added to typing_extenions>=4.6.0.

How can we reproduce the bug?

pip install typing_extensions==4.5.0
python -c "from typeguard import check_type"

Typeguard already depends on typing_extensions >= 4.10.0, so I have no clue why you would report this as a bug.
