    Better warning and instructions in case someone runs emulated Python (#25482)
    
    It seems that the problem with runnig an emulated Python with rosetta
    on Macs M1/M2 might be more widespread. There are various scenarios
    where people could get the emulated Python:
    
    * Installing application with pre-bundled Intel Python (Intellj/PyCharm)
    * Installing older Python via anaconda
    * Transferring the configuration from Intel based Macs (yes, Apple
      will NOT warn you when you are copying brew, python and other
      binaries during the Apple-blessed "Transfer my Mac").
    
    This means that proably quite a number of people currently runs
    Intel, emulated version of Python on their shiny new M1s which
    slows the Python (and thus Airflow) more than 10x.
    
    We alredy had a warning about it, but now it is more explicit, telling
    the user what exactly should be checked and how to rectify from
    the situation (basically nuking the development environment including
    brew and restarting from scratch is the best option you have).
    
    (cherry picked from commit ee03c2b693577d72365baa47d5209f1246e405b3)
