Fix warning QF1004 of staticcheck

[mamo3gr]

Problem

A linter Staticcheck, which could be included in golangci-lint, warns QF1004 in the generated code:
https://staticcheck.dev/docs/checks/#QF1004

Use strings.ReplaceAll instead of strings.Replace with n == -1

Solution

Do what the linter says.
There seems not to be any drawback so all replacement are applied in an automatic manner (including test data).
