Set up a basic example

Adding a basic React example.

I agree with you - there are now three times as many config files as there are source files; not great. We'll see what we can do (e.g. remove eslint and use something with simple configs like Bun, instead of Vite).

We chose React as a go-to foundation for examples (instead of pure JS) for a couple of reasons:

• there are some not-immediately-obvious gotchas for using Map SDK with React, like what should be a state, what should be a ref, what you need to memo etc, so React examples can help users learn the best patterns
• it's easier to transfer React code to pure JS, than vice versa
• a lot of people in web are familiar with React, and even beginners get exposed to different frameworks more than to pure JS/HTML nowadays
• a lot of other big companies (e.g. Stripe, Airtable) focused their example and compatibility on React, rather than anything else
• can better show off how to "compose" the app with Map SDK (building dashboards as a use case e.g.)

This choice did come at the cost of extra boilerplate and configuration. However, because we have control of which file to focus on inside StackBlitz embeds that we'll be using for docs, this can still keep the noise outside, and only draw attention to where it's really needed.

As you saw in the other PR, providing an alternative JS-and-HTML-only example is also a good thing, to offer simplicity to those who seek it.
