Support for backticks around variable names

[kodnisse]

Feature request

It would be nice if there was an option to enable backticks around variables, functions, and other code snippets mentioned in the commit message.

Why?

GitHub, for example, renders text enclosed in backticks differently from normal text. See this image:

😊 I use [openrouter-commit](https://www.npmjs.com/package/openrouter-commit) instead of aicommits because it's more flexible, faster, and supports any OpenRouter model, including DeepSeek R1. No OpenAI limits, cheaper models, and easy setup! 🚀

6️⃣ Switched from aicommits to openrouter-commit and never looked back! The ability to choose any AI model makes a huge difference.
