`userDataDir` has unexpected results

Environment:

• OS: Windows 10
• Extension: 1.3.1

Describe the bug:

Setting vscode-edge-devtools.userDataDir does not work as expected.

Repro steps:

// opens default temporary profile
"vscode-edge-devtools.userDataDir": false,
"vscode-edge-devtools.userDataDir": "C:/Users/Enteleform/AppData/Local/Microsoft/Edge/User Data/Profile 2",
"vscode-edge-devtools.userDataDir": "C:/Some/Invalid/Path",

// opens `Enteleform/Profile 2`
"vscode-edge-devtools.userDataDir": "C:/Users/Enteleform/AppData/Local/Microsoft/Edge/User Data",

Expected behavior:

// opens `Enteleform/Profile 1`
"vscode-edge-devtools.userDataDir": false,

// opens `Enteleform/Profile 2`
"vscode-edge-devtools.userDataDir": "C:/Users/Enteleform/AppData/Local/Microsoft/Edge/User Data/Profile 2",

// shows an error message informing user to use the path of a valid profile directory
"vscode-edge-devtools.userDataDir": "C:/Some/Invalid/Path",

// same as the previous example, unless one of the suggestions below is implemented
"vscode-edge-devtools.userDataDir": "C:/Users/Enteleform/AppData/Local/Microsoft/Edge/User Data",

Suggested behavior:

// - remove the `false` option
// - add the following options, which are more explicit and provide context as to their outcome

// opens `Enteleform/Profile 1`
"vscode-edge-devtools.userDataDir": "default",

// shows a dropdown to select one of the available user profiles @ `%LocalAppData%/Microsoft/Edge/User Data`
"vscode-edge-devtools.userDataDir": "select",

// shows a dropdown to select one of the available user profiles @ the defined path
"vscode-edge-devtools.userDataDir": "C:/CustomPath/Edge/User Data",

Start by reproducing the reported vscode-edge-devtools.userDataDir behavior on Windows 10 with the listed valid, invalid, and profile-directory paths. Compare the observed profile selection and error handling with the expected behavior, then determine whether the proposed default, select, and custom-path options are in scope. Done means valid profiles open predictably and invalid paths provide a clear error.
