Added support for bicep files in AzureResourceManagerTemplateDeploymentV3

[t-dedah]

Task name: AzureResourceManagerTemplateDeploymentV3

Description: Added support for biceps files in case of "Linked artifact" templateLocation. Local bicep file is converted into a json file using az bicep build --file <filepath> which is used for further deployment.
As bicep was added in azure cli 2.20.0, any agent using version less than 2.20.0 will not be able to deploy bicep files. Installation step for bicep CLI can be added later.

Documentation changes required: Y

Added unit tests: Y

Attached related issue: Y - #15337

Just a few minor wording suggestions.

Added some comments! I'm reviewing from a 'does this invoke Bicep in the correct way?' perspective, so I'm not looking at code style/maintainability - I'd expect that review to come from someone on your team.

Thanks for adding this much-desired functionality! The Bicep invocation logic & tests look good to me. I've not really reviewed for code style & maintainability - I expect that review to come from one of the owners of this repo.
