[Operator] Add docs for instrumenting Deno

[lucacasonato]

Also see open-telemetry/opentelemetry-operator#3613

This adds documentation for using the operator to instrument Deno applications by setting OTEL_DENO=true and then injecting with instrumentation.opentelemetry.io/inject-sdk: "true".

TIL that deno comes with otel support, wow!

We normally default to not allow documentation for non official otel projects, e.g. we have https://opentelemetry.io/docs/languages/other/ to list 3rd party implementations and language interest (which needs some love and attention from what I just see), but having a language provide out of the box support is very much in line with otel's mission & vision, so we should address that accordingly.

@lucacasonato thank you for bringing this to our attention, we need some time to think about that and address this properly.

From the operator perspective, the content looks good to me. I'm also very happy with the runtime having first-party Otel support.

Copyedit pass. See inline suggestions.

Let's keep the sections in alphabetical order: @lucacasonato - could you please move the Go section to be right after the new Deno section?

LGTM pending @chalin approval

LGTM

Thanks folks.

It looks like the static site generator does not support links inside of "notes":

[chalin]

Oops, I missed that :-/. It does, but the link definition needs to be inside the note. Can you submit a followup PR @lucacasonato?
