Python jobs on PS platform: executable issues

Autosubmit Version

4.1.x (tested .5 and .6)

Which task has issues?

autosubmit run

Summary

When a task is run with type python on a PS platform, it is executed with the command nohup python <filename>, which can easily break due to not finding the correct executable. This is also the case, if an executable is supplied with the EXECUTABLE field.

Steps to reproduce

autosubmit expid -dm -H <PSARCH> -d "Test exp for python bug report".
Add TYPE: python to one job, e.g. INI.
OPTIONAL: Add EXECUTABLE: /path/to/my/python3 to the job
autosubmit create <expid>
autosubmit run <expid>

What is the current bug behavior?

The job INI fails with the error nohup: failed to run command 'python': No such file or directory.

What is the expected correct behavior?

It should use python3 or the provided executable to run the job.
