terminal.launchArgs not being used

[freeskier93]

Type: Bug

Behaviour

python.terminal.launchArgs specified in the settings (workspace or user) are not being added when running a Python script. Reverting back to v2024.22.2 results in the arguments being added as expected.

Example Arguments:

"python.terminal.launchArgs": [
        "-m",
        "pytest",
        "-s"
]

Steps to reproduce:

1. Define arguments in pythong.terminal.launchArgs
2. Run Python script
3. Arguments are not being added in terminal command executing script

You have Python Envs extension, this setting is not yet supported there. Moving this there to add support for this.

Oh, interesting. Thanks for moving it over.
