Highcharts: `javascript:` URL in credits.href runs script on click

Description

A credits.href value beginning with javascript: is assigned to the window location when the credits label is clicked, without being checked against an allowed-scheme list. An attacker who controls the chart configuration can therefore run script in the origin of the page hosting the chart.
