[bug] "Run > Add Configration" activates the python extension in non-python projects #25825
Description
Type: Bug
Normally, python extension should not be activated in this case, as it will affect the programming experience of other language projects. The reason why I installed the python extension but not the python environment is because I log in to the same account on my two computers, and the extensions will be synchronized, one computer needs the python environment and the other computer does not.
Behaviour
The extension is activated and prompts "No Python found. Would you like to install uv and use it to install Python? This will download and run an installer from https://astral.sh."
Steps to reproduce:
- prepare a computer without python environment installed
- create a folder and open it with vscode
- Run > Add Configration
- wait for a while
Diagnostic data
Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
