[BUG] miss makezero in slice init

[alingse]

I was running github actions to run linter makezero for top github golang repos.

see issues https://github.com/alingse/go-linter-runner/issues/1

and the github actions output https://github.com/alingse/go-linter-runner/actions/runs/9243197843/job/25427030599

====================================================================================================
append to slice `_gcgeg` with non-zero initialized length at https://github.com/unidoc/unipdf/blob/master/model/model.go#L4714:1[9](https://github.com/alingse/go-linter-runner/actions/runs/9243197843/job/25427030599#step:4:10)2
====================================================================================================

the _gcgeg :=make ([]string ,len (_ebebe ._cbag .Keys ())) should be _gcgeg :=make ([]string , 0,len (_ebebe ._cbag .Keys ()))
