TransformLegacyDocument adds requireParametersWithoutDefault which is not saved #5303
Description
When the nswag document contains the text "nobuild:", the TransformLegacyDocument method adds "requireParametersWithoutDefault": true and sets saveFile=true
This property is not loaded and/or saved by the LoadDocument+SaveAsync calls in the LoadAsync method.

When the attached file is processed by NSwag.Console, the file is transformed and saved on every execution.
We ran into this issue as the relative paths in our nswag.json were modified (adding extra "..\") causing subsequent builds to fail. See related issue #1886.
