Fix missing icon due to naming

[infamy]

This renames the icon that was named with TA.svg, you have code that only caps the first letter, so Ta.svg is what it expects.

Line 84 of script.js

            if (category === 'heads') {
                actualFilename = `Screw_Head_-_${filename.split('-').map(word => 
                    word.charAt(0).toUpperCase() + word.slice(1)
                ).join('_')}`;
            }

This resolves the Ta head showing up as a broken image.
