Honor the OS's cursor blink settings

### Expected

Simplenote-electron desktop app should honor Windows 10 level cursor blink settings.

Using Windows and Firefox as an example, here is what should be happening (thanks @jonathansampson for the gif):

This issue may be relevant:
https://github.com/electron/electron/issues/10668

### Observed

The cursor still blinks. The choices made by the user in his/her Windows 10 settings are ignored.

### Reproduced

On Windows:
Open settings, search for “cursor blink rate", (brings up "Keyboard Properties"), under "Speed" tab in section "Cursor blink rate" move the slider all the way to the left.

### Where did you see the bug

- OS: Windows
- OS version: 10
- Simplenote app version: 2.21.0

Thank you.

Start with the Electron issue linked in the report and reproduce the behavior using Windows 10's Keyboard Properties cursor blink rate setting. There are no repository files or tests named in the issue; done means the desktop app follows the user's Windows cursor blink setting, including disabling blinking when the rate is set to the far left.
