PATH user environment variable is incorrectly transmitted to the IPython Console for macOS shortcuts

[mrclary]

When launching Spyder via shortcut on macOS, the PATH environment variable passed to the IPython Console is incorrect.
This is due to

spyder/spyder/plugins/ipythonconsole/utils/kernelspec.py

Lines 165 to 168 in 380e844

	# Ensure that user environment variables are included, but don't
	# override existing environ values
	env_vars = get_user_environment_variables()
	env_vars.update(os.environ)

introduced by #21065.

I think that the user environment variables should take precedence over the Spyder runtime environment variables. I do not know of any reason why it should not be this way.

I think that the user environment variables should take precedence over the Spyder runtime environment variables.

Sure, I agree with that. So, do you propose to change that code to be something like this?

env_vars = os.environ.copy()
env_vars.update(get_user_environment_variables())

Precisely.

Ok, please open a PR to implement that change then.
