[Feature Request]: Minimize the number of 'modules' hardcoded occurrences

[eriqua]

Description

Related to #1127

Decrease the number of relative modules path (currently 'modules') hardcoded occurrences in the repository.

Suggestion: use a global variable to be leveraged by utilities, GitHub actions, ADO pipeline templates, global tests.

Hardcoded occurrences will stay for pipeline trigger paths due to how global variables are retrieved only after pipelines are triggered.
