Auto darkmode does not work

[MG-5]

Describe the bug
The auto darkmode does not get the system darkmode, its always light.

To Reproduce
Steps to reproduce the behavior:

1. Set system/browser theme to dark.
2. If neccessary, clear browser session cache
3. Open website
4. See light site

Expected behavior
System dark mode leads to dark website

Additional context
I already fixed the problem in my case.

Line 38-40 in dark-mode.js

Type-on-Strap/assets/js/partials/dark-mode.js

Lines 38 to 40 in 6c9d166

	browserPrefersDark.addEventListener('change', () => {
	if (browserPrefersDark.matches) sessionStorage.setItem('theme', 'dark')
	});

creates an event handler, which is not triggered at the begin, so few lines later the session storage is always set to light cause of undefined sessionPrefers

Type-on-Strap/assets/js/partials/dark-mode.js

Line 45 in 6c9d166

setMode(sessionPrefers ? sessionPrefers : 'light')

You can fix the issue by adding the line

if (browserPrefersDark.matches) sessionStorage.setItem('theme', 'dark'); 

before the event handler. (like here)

(I could have created a PR with the fix myself, but I couldn't get gulp to work for generating main.min.js a folder above it.)

Thanks for your input! Would you want to make a PR for it? (Since you already fixed it)

If you have no problem, that I would edit the main.min.js manually? ;)
