fix: window.open popups are always resizable
Closes https://github.com/electron/electron/issues/43591.
Per current WHATWG spec, the `window.open` API should always
create a resizable popup window. This change updates the
`parseFeaturesString` function to ensure that windows opened
with `window.open` are always resizable, regardless of the
`resizable` feature string.
