Based on pylint's message ``consider-iterating-dictionary`` suggestion.
Surprisingly using a dict or set comprehension instead of a new temp var is
actually consistently slower here, which was not intuitive for me.
```python
from timeit import timeit
families = {1: {"testcase": [1, 2, 3, 5, 8]}}
attrs = {1: "a", 2: "b", 3: "c", 4: "d", 5: "e", 6: "f", 7: "g", 8: "h"}
class Old:
def old(self):
self.attrs = attrs
temp_attrs = {}
for key in self.attrs.keys():
if key in families[1]["testcase"]:
temp_attrs[key] = self.attrs[key]
self.attrs = temp_attrs
class OldBis:
def old(self):
self.attrs = attrs
temp_attrs = {}
for key in self.attrs:
if key in families[1]["testcase"]:
temp_attrs[key] = self.attrs[key]
self.attrs = temp_attrs
class New:
def new(self):
self.attrs = attrs
self.attrs = { # Even worse with k: v for k in self.attrs.items()
k: self.attrs[k] for k in self.attrs if k in families[1]["testcase"]
}
if __name__ == "__main__":
n = 1000000
print(f"Old: {timeit(Old().old, number=n)}")
print(f"Just removing the keys(): {timeit(OldBis().old, number=n)}")
print(f"List comp, no temp var: {timeit(New().new, number=n)}")
```
Result:
Old: 0.9493889989680611
Just removing the keys(): 0.9042672360083088
List comp, no temp var: 0.9916125109884888
It's also true for the other example with similar benchmark, but the exact
code probably does not need to be in the commit message.

ruff is faster and handle everything we had prior.
isort configuration done based on the indication from
https://github.com/astral-sh/ruff/issues/4670, previousely based on
reorder-python-import (#11896)
flake8-docstrings was a wrapper around pydocstyle (now archived) that
explicitly asks to use ruff in https://github.com/PyCQA/pydocstyle/pull/658.
flake8-typing-import is useful mainly for project that support python 3.7
and the one useful check will be implemented in https://github.com/astral-sh/ruff/issues/2302
We need to keep blacken-doc because ruff does not handle detection
of python code inside .md and .rst. The direct link to the repo is
now used to avoid a redirection.
Manual fixes:
- Lines that became too long
- % formatting that was not done automatically
- type: ignore that were moved around
- noqa of hard to fix issues (UP031 generally)
- fmt: off and fmt: on that is not really identical
between black and ruff
- autofix re-order in pre-commit from faster to slower

Setting `norecursedirs` overrides the default, so we end up scanning
dot-directories and such which slows down collection unnecessarily
(150ms on my working directory).
this issues is less likely to hit due to the recent regendoc release
which includes a wheel
* migrate to setuptools_scm 6.3.2
* use SETUPTOOLS_SCM_PRETEND_VERSION_FOR_PYTEST
