Bump pytest-xvfb from 2.0.0 to 3.1.1

[dependabot]

Bumps pytest-xvfb from 2.0.0 to 3.1.1.

Changelog

Sourced from pytest-xvfb's changelog.

v3.1.1

• Same as v3.1.0, but with proper version number and fully released.

v3.1.0

• Support for Python 3.7 and 3.8 is now dropped, while official support for 3.12 and 3.13 was added (with no code changes required).
• pytest.ini (required to run self-tests) is now included in sdists (#39).
• New pytest_xvfb_disable hook to dynamically disable pytest-xvfb.

v3.0.0

• New --xvfb-backend argument, which can be used to run Xephyr or Xvnc in place of Xvfb (e.g. for visual inspection but on a remote system or a consistent screen size needed).
• Support for Python 3.5 and 3.6 is now dropped, while official support for 3.9, 3.10 and 3.11 was added (with no code changes required).
• The Xvfb instance is now no longer saved in pytest's config object as config.xvfb anymore, and only available via the xvfb fixture.
• Xvfb is now shut down as late as possible (via an atexit hook registered at import time), seemingly avoiding errors such as "XIO: fatal IO error 0 (Success)".
• Code reformatting using black/shed.
• Packaging refresh using pyproject.toml.
