[BUG] docstring for functions is broken

[jpaillard]

The docstring of functions does not render correctly in the API. See for instance: https://hidimstat.github.io/dev/generated/api/class/hidimstat.cfi_analysis.html#hidimstat.cfi_analysis

Indeed, do you understand why ?

It seems that the new line was not interpreted.
For this, you need to check the function _aggregate_docstring or _reindent in https://github.com/mind-inria/hidimstat/blob/main/src/hidimstat/_utils/docstring.py
