Improve styling of premiere date box (#2611)

* use 5px border radius instead of 5%

a 5% border radius will create an oval shape when height and width differ.
this doesn't look good.
5px radius looks better and is used in other places

* offset premiereDate by 12px from bottom left

Increases the offset a tiny amount and adds a left offset aswell.
This looks better than when it was previously only offset from the bottom.
I used 12px because it's what youtube uses.

* use flexbox to align items additional positioning with margins

vertically centes premiere icon and text with by making their parent a flexbox

sets a min width for the text instead of using a set width for the premiereDate

* change font size and weight of timestamp text

* remove uneeded line height styling

line height 1.2 did not affect anything

* fix indentation

* Update src/renderer/views/Watch/Watch.sass
