being Github.

Issue #, if available:

## Description

Description of changes:
- added new parameter `alzCicdPlatform` to New-ALZEnvironment.ps1
@picccard
- moved accelerator readme to be the first reference @picccard @picccard
- moved yml files for CI/CD to its own property in the config file
@picccard
- added v0.15.0 config file and updated all references within module
- updated readme.md with example for New-ALZEnvironment with Azure
Pipelines

## Breaking changes
This feature will not break any functionality, as the parameter has
'github' as default.
If you were to run the accelerator with the parameter set to
'azuredevops' you would only see the [this
warning](https://github.com/Azure/ALZ-PowerShell-Module/blob/11c0b6f66bc3f31de660167f237ddbc28370f553/src/ALZ/Private/Copy-ALZParametersFile.ps1#L29)
telling you the files are not found and end up without any .azuredevops
folder in the desired OutputDirectory / alzEnvironmentDestination
