Task command surround by single quite (') lead to syntax error on VSC 1.64.0

[Massukio]

Does this issue occur when all extensions are disabled?: Yes/No
Yes

• VS Code Version: 1.64.0
• OS Version: Windows 10 Pro 64-bit

Steps to Reproduce:

1. Using the custom task.json to run task

"version": "2.0.0",
    "tasks": [
        {
            "label": "Run File - Robot Pure (CMD)",
            "windows": {
                "command": "${workspaceFolder}\\.venv\\Scripts\\activate && python -m robot",

            },
            "linux": {
                "command": "source ${workspaceFolder}/.venv/bin/activate && python -m robot"
            },
            "args": [
                "--loglevel", "TRACE:INFO",
                "--outputdir", "report",
                "${file}"
            ],
            "type": "shell",
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "reveal": "always",
                "panel": "new",
                "focus": true
            },
            "options": {
                "cwd": "${workspaceFolder}",
                "env": {
                    "PYTHONIOENCODING": "UTF-8",
                    "PYTHONPATH": "${workspaceFolder}",
                    "PATH": "${workspaceFolder}/.venv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:"
                }
            }
        },
]

2. The task run successfully on VSC 1.63.2
   But failed on VSC 1.64.0 and got syntax error

File name, directory name or volume label syntax is incorrect

Investigating the commands VSC executed, and find the difference below
VSC 1.63.2:
The command surround by Double Quotes on 1.63.2 which can be run successfully

The terminal process "C:\WINDOWS\System32\cmd.exe /d /c "...\.venv\Scripts\activate && python -m robot" --loglevel TRACE:INFO --outputdir report Test.robot"

VSC 1.64.0:
The command surround by Single Quotes on 1.64.0 which caused syntax error

The terminal process "C:\WINDOWS\System32\cmd.exe /d /c '...\.venv\Scripts\activate && python -m robot' --loglevel TRACE:INFO --outputdir report Test.robot"
