fix(core-logger-pino): show log levels <= defined threshold level

[air1one]

Summary

Show log levels <= defined threshold level, as our custom levels are defined from higher 0 "emergency" to lower 7 "debug".

So that if I define the threshold as "info" / 6, I want everything below or equal to 6 to be shown (higher levels), and everything above to be hidden (lower levels).
