Golangci-lint @ v2

[bernot-dev]

Currently, vim-go supports golangci-lint@v1. golangci-lint@v2 was recently released.

This issue requests support for golangci-lint@v2.

Key issues to address:

1. Install github.com/golangci/golangci-lint/v2/cmd/golangci-lint@latest instead of v1.
2. Replace --print-issued-lines=false with --output.text.print-issued-lines=false.
3. Remove --exclude-use-default=false as this is now the default behavior.
4. Fix file paths. File paths are now relative to the .golangci.yml config file by default, typically at the project root. Current behavior results in duplicating the path. For example <root>/pkg/foo/bar.go >> <root>/pkg/foo/pkg/foo/bar.go.

golangci-lint v2 now has a new golangci-lint fmt command, it would be cool to be able to use it for formatting operations, sorting imports...
