Subject: [PATCH] Update `perf` workflow for OTP26

Scheduler names changed in OTP26, so we need a different `sed` expresion
to merge data from all schedulers. The example is now compatible with
versions prior to OTP26 and OTP26+

 Using the same data we can also produce a graph where the scheduler profile data
 has been merged by using `sed`:
 
-    ## Strip [0-9]+_ from all scheduler names
-    sed -e 's/^[0-9]\+_//' out.folded > out.folded_sched
