fix: Fixed a set of endpoints where inputs were escaped and should not be escaped

Hello Team 👋

With the factorization of HTTP calls with do function in this commit, we introduced a regression regarding input strings not escap'ed before the refactoring.

This merge request aims to add back the missing NoEscape.

Impacted endpoints were:

• GetLicenseTemplate
• SetGroupCustomHeader
• DeleteGroupCustomHeader
• SetGroupHookURLVariable
• DeleteGroupHookURLVariable
• EditPipelineScheduleVariable
• DeletePipelineScheduleVariable
• ListTemplates
• GetProjectTemplate

Closes #2225 (closed).
