Add support for executing golangci-lint using go run method

[artuross]

Welcome

• Yes, I understand that the GitHub action repository is not the repository of golangci-lint itself.
• Yes, I've searched similar issues on GitHub and didn't find any.

Your feature request related to a problem? Please describe.

This action already supports detecting version from go.mod file when version param is not set, but the golangci-lint binary is still downloaded from the internet. This may be unwanted for security reasons, but also since Go is already aware of what makes up golangci-lint executable, I believe a better approach would be to use Go to run the binary.

Describe the solution you'd like.

Instead of fetching binary version from the internet, it can be run as go run github.com/golangci/golangci-lint/cmd/golangci-lint ... which will use the version defined in Go modules.

Describe alternatives you've considered.

• current approach with downloading binaries from the internet
• specifying custom download path
