Merge branch 'issuable-sidebar-bold' into 'master'

Fixed issue with bold in issuable sidebar

## What does this MR do?

~~The sidebar contained both normal font weight & bold font weight, so this standardises them to bold.~~

After looking at the designs, i've updated the font weights & colors throughout the sidebar to correctly match them

## Screenshots (if relevant)
