docs(sdk): update earliest support node version

[svetlanabrennan]

Signed-off-by: Svetlana Brennan svetlana.svn@gmail.com

Which problem is this PR solving?

Spans use performance.timeOrigin in perf_hooks to create startTime and endTime but performance.timeOrigin is set incorrectly before v8.12.0. Node introduced a fix for it that was backported to v8.12.0.

Fixes Issues # 2857 & 2834

Short description of the changes

Updated node support section in the sdk readme to say 8.12.0 as the earliest supported node version.

I think we should update the minimum version there: https://github.com/open-telemetry/opentelemetry-js/blob/main/packages/opentelemetry-sdk-trace-node/package.json#L33

Just in that package? Or in all the packages?
