explicit-preview-rules does not work for fixes

[hauntsaninja]

I'd expect both runs of ruff below to fix the error

~/tmp/repro λ ruff --version
ruff 0.1.9

~/tmp/repro λ cat asdf.py
lists = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
sum(lists, [])
~/tmp/repro λ cat pyproject.toml
[tool.ruff]
select = ["RUF017"]
[tool.ruff.lint]
preview = true
explicit-preview-rules = true
~/tmp/repro λ ruff asdf.py --fix --unsafe-fixes
asdf.py:2:1: RUF017 Avoid quadratic list summation
Found 1 error.

~/tmp/repro λ vim pyproject.toml
~/tmp/repro λ cat pyproject.toml
[tool.ruff]
select = ["RUF017"]
[tool.ruff.lint]
preview = true
~/tmp/repro λ ruff asdf.py --fix --unsafe-fixes
Found 1 error (1 fixed, 0 remaining).

Thanks for the report! My assumption is that the fixable setting which defaults to ALL is not including the preview rule since it is not explicit. We should probably exempt fixable from these semantics.
