[semconv] update template to remove deprecated semconv attributes (#10829)

This PR is updating the jinja template to ignore deprecated attributes
as was done in
open-telemetry/opentelemetry-go#5476.
Additonally, generate v1.26.0 semconv package

This replaces
#10249

Fixes
#10813

NOTE: This leaves empty resource/trace/event files, but I'd rather not
remove the methods they expose in this change
