How did you install golangci-lint?

Official binary

Description of the problem

We are seeing build failures from custom plugin builds in our CI when upgrading to v2.5.0:

Error: build process: build golangci-lint binary: custom version: hash plugin directory: read /home/runner/work/pulumi-service/pulumi-service/infrastructure/bin: is a directory

It looks like this error was introduced in #5896. The exact error is non-determanistic, there's multiple things in our repository that don't hash well. node_modules has some invalid symlinks as does a Go vendor folder, and we have a bunch of build artifacts in bin that don't need to be hashed, including a local copy of golangci-lint. This results in a custom build that takes a long time (from trying to hash things that should not be hashed) then fails.
