Use a better way of pinning the version of golangci-lint

Instead of requiring the user to install the right version of the tool in their
.bin folder, create a shim that automatically runs the right version of the
tool. This has several benefits:
- it works out of the box with no setup required (the tool will be automatically
  downloaded and compiled the first time it is used)
- no work needed for developers when we bump the golangci-lint version
- it works in working copies that are used in different environments (e.g.
  locally on a Mac, or inside a dev container)
