Currently pointed at a local snapshot so CI will definitely fail, as otel4s main has NoPublish for everything involving the SDK

@iRevive Updated all the attributes and removed semconv-experimental

Would appreciate another look when you have time

@alexcardell the changes look good.

We still need to wait for a release of https://github.com/http4s/http4s-otel4s-middleware, right?

[alexcardell]

The middleware would be useful for the example, but I don't believe it's necessary otherwise

[iRevive]

There is a compatible pre-release of the http4s-otel4s - https://github.com/http4s/http4s-otel4s-middleware/releases/tag/v0.9.0-rc.2.

Hi, is there anything blocking this PR ?

[iRevive]

I think we need to wait for a new release of the http4s-otel4s-middleware

[alexcardell]

It's fixed for 0.13.x

[alexcardell]

Updated for 0.14.x
