http.proxy in vscode is not set for build/upload task

[yyjdelete]

In current version, installer for platform.io follows http.proxy settings in vscode, but build task and upload task(which may download some toolchains/frameworks/platform resource for the first time) start from another process from vscode don't follow it https://github.com/platformio/platformio-vscode-ide/blob/e116c580b703c8749767a59fe42b097bff66aa4a/src/main.js#L126-L150

Should the above logic also be added here? https://github.com/platformio/platformio-vscode-ide/blob/2ed0070f71c27a1251cb3a1bdd97ede1006875c4/src/project/tasks.js#L111-L116
