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
+ ## Strip [0-9]+_ and/or _[0-9]+ from all scheduler names
+ ## scheduler names changed in OTP26, hence two expressions
