refactor: redefine Nat.mod such that rfl : 0 % n = 0

fix: add done alternative to decreasing_with ( #2019 )
...
Previously `decreasing_with` failed if `simp_wf` closes the goal on its
own. This can cause undesired regressions when new `simp` lemmas are
introduced.
Closes #2018 .

chore: rename le_or_eq_or_le_succ ( #2024 )
...
Rename `le_or_eq_or_le_succ` `le_or_eq_of_le_succ`. We need to change
its name in `Std/Data/Array/Init/Lemmas` and `Std/Data/Array/Lemmas`.

doc: replace maximum? in minimum? docstring
...
This is my first contribution, if it can be counted as a contribution. Following the [documentation for simple fixes](https://github.com/leanprover/lean4/blob/master/CONTRIBUTING.md#simple-fixes ), I opened the PR directly instead of discussing in the zulip or opening an issue. Hope that's ok.
