docs(taplo): add toml formatter

[bearomorphism]

Description

I noticed that I accidentally introduced unexpected style change in pyproject.toml (50fd65f), so I think it would be better if we have a consistent toml formatter.

Expected Behavior

Pre-commit hook now has taplo and it should work even without installing taplo locally.

Steps to Test This Pull Request

1. Randomly insert white spaces in pyproject.toml and save without formatting to make the formatting bad.
2. git commit
3. The broken format should be fixed.

You mean this one? But it seems to be a one-liner still

[bearomorphism]

I didn't find a good combination of options to keep the file unchanged.

[bearomorphism]

If I set array_auto_collapse = false then someone with their formatter can still make it a one-liner.

[bearomorphism]

If I set column_width = n for some n < 80 then taplo introduces more changes.

I'm okay with this one, but I will let @woile or @noirbizarre decide whether we need it.
