Fixes all our Go file imports to match the preferred spec that we've _mostly_ been using. For example: ``` import ( "context" "time" "github.com/prometheus/client_golang/prometheus" "golang.org/x/xerrors" "gopkg.in/natefinch/lumberjack.v2" "cdr.dev/slog/v3" "github.com/coder/coder/v2/codersdk/agentsdk" "github.com/coder/serpent" ) ``` 3 groups: standard library, 3rd partly libs, Coder libs. This PR makes the change across the codebase. The PR in the stack above modifies our formatting to maintain this state of affairs, and is a separate PR so it's possible to review that one in detail.
