inline-snapshot is not able to format your code.
This issue can be solved by:
* installing inline-snapshot[black] which gives you the same formatting like in
older versions
* adding a `format-command` to your pyproject.toml (see \n\
https://15r10nk.github.io/inline-snapshot/latest/configuration/#format-command \n\
for more information).
