Fix lint errors: format Go code

[Copilot]

Code formatting check was failing due to unformatted Go test file.

Changes

• Ran make fmt to align struct field formatting in pkg/workflow/action_pins_test.go

// Before
{
    name: "empty steps slice",
    steps: []any{},
    wantErr:   false,
    wantCount: 0,
},

// After  
{
    name:      "empty steps slice",
    steps:     []any{},
    wantErr:   false,
    wantCount: 0,
},
