Update 1.5

This is a major update to the theme which primarily updates the framework underlying the theme (Bootstrap) to version 5. This update is a drop-in replacement and does not require any major changes to a WordPress site using a previous version of Bootscout.

A full changelog is as follows:

• Updated to Bootstrap 5 and made dependency updates and style updates to support the update
• Updated link style to be consistent with each other and fix a few known issues
• Updated search widget to bring it back in alignment with navbar search
• Added Scout section colour to theme
• Removed extra elements from footer
• Updated align-wide class to work better on smaller screens
