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

[stefanhaller]

• PR Description

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)

Approach suggested by @kyu08.

Replaces #4729.
