Plugin fails to generate new project on Ubuntu 24.04

[pradeepa-s]

Plugin version: v0.15.2

Description:

When trying to generate the project the toolchain download seems not working.
I noticed this time to time, but it seems persistent now and I can't seem to create new projects at all.

This looks similar to #76 but, I don't get the failure message. It just tries to download the toolchain and somehow failing.

Steps to re-produce:

1. Delete the .pico_sdk folder
2. Open vscode and start the extension
3. Create a new project
4. The 'Downloading SDK and Toolchain' status message pops up
5. Wait for 5 mins
6. The 'Downloading SDK and Toolchain' status message wouldn't complete
7. Examining the .pico_sdk shows three folders

MS-7D91:~$ tree -L 2 .pico-sdk/
.pico-sdk/
├── cmake
│   └── pico-vscode.cmake
├── sdk
│   └── 2.0.0
└── toolchain
    └── 13_2_Rel1

6 directories, 1 file

8. Toolchain folder has no content

MS-7D91:~$ ls -al .pico-sdk/toolchain/13_2_Rel1/
total 8
drwxrwxr-x 2 pradeepa pradeepa 4096 Sep 10 08:15 .
drwxrwxr-x 3 pradeepa pradeepa 4096 Sep 10 08:15 ..

9. Examined vscode console and found the following message.

[Extension Host] [raspberry-pi-pico] https://github.com/raspberrypi/pico-sdk.git 2.0.0 has been cloned and installed.

10. Restarted vscode and started to generate the project again. Same result, but the console says SDK 2.0.0 is alrady installed

[Extension Host] [raspberry-pi-pico] SDK 2.0.0 is already installed.

It just takes ~40 mins to download. That's the reason why I though it failes.
