<!-- This issue template can be used as a great starting point for feature requests. The section "Release notes" can be used as a summary of the feature and is also required if you want to have your release post blog MR auto generated using the release post item generator: https://about.gitlab.com/handbook/marketing/blog/release-posts/#release-post-item-generator. The remaining sections are the backbone for every feature in GitLab.
The goal of this template is brevity for quick/smaller iterations. For a more thorough list of considerations for larger features or feature sets, you can leverage the detailed [feature proposal](https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Feature%20proposal%20-%20detailed.md). -->
### Problem to solve
Enable Syntax highlighting for `.bicep` files ([Azure Bicep](https://learn.microsoft.com/en-us/azure/azure-resource-manager/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
