Ruff basic examples

[EwoutH]

Run ruff and ruff format on the basic examples. Follow-up on #2365, as requested.

I fixed all the non-docstring errors, but there are still 56 docstring errors left:

• D100 Missing docstring in public module — 14 occurrences
• D102 Missing docstring in public method — 15 occurrences
• D103 Missing docstring in public function — 9 occurrences
• D107 Missing docstring in __init__ — 4 occurrences
• D205 1 blank line required between summary line and description — 5 occurrences
• D417 Missing argument descriptions in the docstring for __init__ — 3 occurrences
• D101 Missing docstring in public class — 1 occurrence

For now we ignore them, but they can be unignored later if preferred.

Also update the pyproject.toml to enforce this (aeac384):

• Only exclude examples/advanced from ruff, to start running ruff on the basic examples.
• Ignore docstring errors in the example folder.

do you mind if I contribute to this directly by fixing the various outstanding issues?

[EwoutH]

Normally, no, but in this case I prefer merging this as is and doing follow-up PRs other issues.

This PR is now neat and atomic, and you can just remove that added line in pyproject.toml in a future PR to see all doc errors again.

Okay, I think it's already much better now, acknowledge not updating docstrings in this PR, but should be done in the future
