### Description

I believe we should enhance the clarity of the section on semantic versioning at https://azure.github.io/Azure-Verified-Modules/specs/shared/#id-snfr17---category-release---semantic-versioning. Currently, it outlines the versioning mechanism broadly. We should specify, particularly for Bicep modules, the need for a version.json file, include a template for contributors, and clarify versioning practices. For instance, if the initial module version in the version.json is 0.1.0, contributors should record it as 0.1. This distinction was initially unclear and could lead to confusion.

"version": "0.1",
"pathFilters": [
"./main.json"
]
