Update examples

[vreynolds]

Which problem is this PR solving?

• moving examples closer to the source of truth

Short description of the changes

• webapp example ported from https://github.com/honeycombio/examples/tree/main/golang-webapp
• still only building the json example in CI because it's a single file, whereas the webapp has a mod file --> needs more thought to figure out how to reference a local version of libhoney

Running locally (go run .) works great! Running in docker though I get a 500 error in the browser. Error in Docker shows "Error connecting to database: dial tcp 172.24.0.2:3306: connect: connection refused", and so event sent to honeycomb is "sql: no rows in result set". Not sure yet what piece is missing for this, and/or if this is specific to my setup.

I also added a comment about updating the endpoint to api.honeycomb, and maybe using the local libhoney-go codepath instead of pulling a specific version from github.

@JamieDanielson the docker error with sql row missing is dues to the browser caching your session from "go run" - it's not the most robust app 😅 if you clear your cookies for localhost:8888, and re-run from docker, it should work 🤞

ah, facepalm. You are absolutely right:
