Demos should allow _any_ tagged meta (or provide a config for allowed metas)

[NullVoxPopuli]

talking about this code: https://github.com/josemarluedke/docfy/blob/main/packages/ember/src/plugins/extract-demos-to-components.ts#L64

Is there a downside to allowing any meta?

Like if the "tab name" were the first meta entry in a code block, are there any downsides?
