Infer golangci-lint version from go.mod

[lukasmalkmus]

For Go projects, I use tools.go to specify the tools the project depends on and pin the version in the go.mod file. This is pretty convenient. It would be awesome to have the action infer the version from the go.mod file. When upgrading, this makes it one file less to update the golangci-lint version.

With some guidance, I can probably tackle this. I'm just completely new to GitHub Actions.

While tools.go is convenient to pin version of dependencies, it might dilute go.mod (or go.sum). I personally used both approach and recently moved away from tools.go. Version pinning is done in Makefile.

Anyway, I have very limited idea how widely tools.go is used. In general, I find it's great idea to derive version from go.mod. This might be done only after #98, which supports patch version.

@lukasmalkmus just curious if you are planning to work on this.

Yes, sounds great. Wil. try to tackle it next weekend 👍

Sorry, I haven't really gotten into it, yet. I made a very simple implementation: #118. It tries to get the version from go.mod if nothing is specified in the action yaml. npm run local runs just fine but I would appreciate some guidance regarding testing.
