Enable `bodyclose` linter (#36168)

Enabe
[`bodyclose`](https://golangci-lint.run/docs/linters/configuration/#bodyclose).
The only issue in non-test code (`services/migrations/dump.go`) was a
false-positive and I think there are a number of undetected cases, but I
guess it's still better than not having it.
