Reproducible linting

[maxitg]

The problem

Currently, our linter is not reproducible. Some linters are not version controlled at all, which causes CI to break over time. But even for ones that are pinned in CI, the version used locally may be different.

Possible solution

To make linting reproducible, we can replace our custom lint.sh script with a tool like Trunk Code Quality.

Alternative solutions

We could try to make reproducible linting ourselves using, e.g., Docker or Bazel, but, given that Trunk is free for open source projects and is really well designed, there isn't really any reason not to use it.
