Bolt v2.3.1 Released

This is a hotfix release that patches two high priority bugs with with the original v2.3.0 release:

• Removed the yarn reference in an NPM script that gets automatically run when installing the older version of the @bolt/components-icons package (fix now switches the command to npm for compatibility) #1107
• Updated the @bolt/components-image Twig template to fix an issue related to auto-escaping #1108

Extra shoutout to @remydenton for his help getting the ball rolling on both of these fixes!
