Description of the change

In the docstrings in duties.py, there are some Example: occurrences, but these should be Examples: (https://mkdocstrings.github.io/griffe/reference/docstrings/#google-section-examples). This issue causes broken document format (https://mkdocstrings.github.io/griffe/guide/contributors/commands/#check-quality, https://mkdocstrings.github.io/griffe/guide/contributors/commands/#check-types ).

Thanks @mushitoriami! I don't understand though, the Example section should definitely work, it should create an admonition. If I load the code with Griffe and parse the docstring, the section is correctly parsed as an admonition 🙃 So I don't understand yet why it's not rendered as such.

Ah, right, I'm dog-fooding the auto docstrings parser, and in this case no style is inferred (so no Google-style admonition parsing). The fix is to either fix the function that infers the style, or set google in mkdocs.yml. Would you like to update the PR?

[mushitoriami]

@pawamoy Thanks for the comment. I've updated to set the style option.

It looks like the CI failure is caused by ty==0.0.52, which was released today.

[pawamoy]

Thanks!
Yeah I'll fix CI elsewhere.

Actually, lets rather add some patterns to the function that infers style. Let me do that in another PR. Thanks again for the report!
