Syntax highlighting for Azure Bicep

Problem to solve

Enable Syntax highlighting for .bicep files (Azure Bicep Code) in the Web UI and the Web IDE.

Proposal

Bicep provides a plugin for highlight.js: https://github.com/Azure/bicep/blob/main/docs/highlighting.md#highlightjs and a monarch plugin which should already be integrated in the Monaco editor: https://github.com/Azure/bicep/blob/main/docs/highlighting.md#monarch

Intended users

Platform Engineers and Developers using Azure Bicep to deploy Azure Resources / Infrastructure.
