Use ruff to format strings to single quotes. (napari#6407)

# Description

Based on a discussion from napari#6386 I updated the ruff configuration to
enable `Q000` https://docs.astral.sh/ruff/rules/#flake8-quotes-q rule
and configured it to use a single quotes string.

We have many double quotes string, but less than single quotes. 

This PR does not change the quotation of docstrings (`"""`) and
multiline strings (`"""`) as they are already enforced by ruff
configuration and could be easy changed.

to see configuration changes please use:
