chore(examples): Convert api-routes-apollo-server example to TypeScript

[maxproske]

Convert api-routes-apollo-server example to TypeScript to match Contribution docs.

• Upgraded to Apollo 3
• As of Apollo 3, apollo-server-micro requires micro dependency, and requires @graphql-tools/schema dependency to call makeExecutableSchema

Documentation / Examples

• Make sure the linting passes by running pnpm lint
• The examples guidelines are followed from our contributing doc

So this supersedes #30082?

[balazsorban44]

I wonder if this is an opportunity to merge api-routes-apollo-server-and-client-auth, api-routes-apollo-server-and-client and api-routes-apollo-server to a single example. What do you think? 🤔

Closing this for now. Got feedback from a maintainer of Apollo Server #30082 (comment)

It sounds like upon release of Apollo Server 4, all Apollo examples should be merged into as few examples as possible, using apollo-server-express and TypeScript.
