Feature request: be able to choose whether to show the snippet's language or not

Currently, each multiline code snippet is prepended with its language, like:

It would be nice if it was possible to hide the language, in case it's not relevant and show just the code snippet. In CLI for Microsoft 365 for example, all snippets are command line so showing shell before each one of them, doesn't add any value.

Right now in 📦 markshell@0.0.6-beta3 it is rendered without language.
