Module readmes - Add bicep parameter usage to module readmes

[MariusStorhaug]

Examples of module implementation are done in JSON both with parameter usage sections in readme.md
files and in different parameter files used for validation deployments.
This makes sense if you are a module developer, however in a "customer first" point of view, CARML is consumed to build solutions with multiple modules. As a solution developer expect I shouldn’t have to do “extra” work with changing quotes form the JSON Example to Bicep that only supports single quotes ‘’.

• Update readme.md parameter usage to show bicep syntax

A separate issue and task is created to explore the feasibility of having bicep based validation deployments.

First create a PoC to see if parameter usage can be derived automatically from parameter files
