Feat: light theme

[Velrok]

Adding light theme as an option

Potential fix for my original request: #131

It looks like this:

Which seams close enough to the reference to me:

Not done

• I've not made changes to the readme mainly because I'd not know how to keep the screenshots consistent.
• I'm not sure what the doc/tags are used for so I left them as is.
• The theme already has a day filter which I'd originally expected to be this actual light theme. But for the sake of not breaking current setups I've not changed that. Maybe something to concider.

This moved because I've sorted the entries alphabetically.

@Velrok This is great man! Well done.
@loctvl842 Please verify and merge this

Great! Maybe "light (filter sun)" could also be added with this.

FYI I found the sun theme in the CSS:

[data-theme=monokai-pro-light-filter-sun] {
    --color-dark2: #d2c9c4;
    --color-dark1: #eee5de;
    --color-background: #f8efe7;
    --color-text: #2c232e;
    --color-accent1: #ce4770;
    --color-accent2: #d4572b;
    --color-accent3: #b16803;
    --color-accent4: #218871;
    --color-accent5: #2473b6;
    --color-accent6: #6851a2;
    --color-dimmed1: #72696d;
    --color-dimmed2: #92898a;
    --color-dimmed3: #a59c9c;
    --color-dimmed4: #beb5b3;
    --color-dimmed5: #d2c9c4;
    --color-panel: #fdf7f3;
    --color-light: #fffcfa
}

So yea could take a look when I have more time.
