chore: upgrade Electron to 41

We don't seem to be affected by breaking changes
electron/website#1030.

Regarding "PDFs no longer create a separate WebContents":
we still disable PDF in WebXDC, disabling mime sniffing.
And overall, I have not investigated this, but it sounds
like a positive security change.

Regarding "Updated Cookie Change Cause
in the Cookie 'changed' Event":
we don't utilize cookies.

I have tested this a little. Works well.
Disabling `IsolateSandboxedIframes` still seems to be required
to make the "connectivity" dialog work.
