refactor(examples): Make all depdendencies into devDeps in the simple…

…mde example (microsoft#23110)

## Description

Switches all dependencies in the simplemde example app to be
devDependencies.

The example apps in the repo are not production code and aren't
published or deployed anywhere. Having prod dependencies in them causes
our lockfiles to mark them as such, and consequently Component
Governance potentially flags them for prod-level security
vulnerabilities. We have one outstanding prod-level alert about the
simplemde package (which seems abandoned); this change should remove the
prod-level severity from it while we migrate to another package for this
example, or get rid of it altogether.

The [ai-collab sample app already showcases this
pattern](https://github.com/microsoft/FluidFramework/blob/main/examples/apps/ai-collab/package.json#L33).
