feat: disable copyloopvar and intrange on Go < 1.22

[ldez]

I propose to disable copyloopvar and intrange for Go < 1.22 to avoid reporting "false-positives" on at least Go 1.21.

$ ./golangci-lint run                                
WARN [linters_context] copyloopvar: This linter is disabled because the Go version of your project is lower than Go 1.22. 
WARN [linters_context] intrange: This linter is disabled because the Go version of your project is lower than Go 1.22. 

The log level is warn because we don't display logs with a lower level (ex: info).
But maybe we can just be quiet and just use the level info 🤔

Note: I know that loopvar can be enabled on go1.21 but if you do that it's better to either use go1.22 or override the Go version inside the golangci-lint configuration and enable the right linters.

Nice, makes a lot of sense! I also don't know what's best here regarding log level but making the user aware must be a good thing I guess. I think the common case for this would be users using enable-all on older Go versions and they can easily just disable the linters to get rid of it just like with deprecated linters.

I forget to add directives on the test files 😄

Sorry for all the commits, switching between 2 Go versions to run tests is a bit painful and confusing.

offtop: let's make an issue?
or how do you track to-do backlog?

I'm currently working on the topic.
