Fix all SVG icons to be 24x24 - 2pts

[chrisvire]

Please regenerate the icons so that they are all consistently 24x24. The SVG is defined at https://fonts.google.com/icons. Please use the following settings:

• filled = 1
• weight = 400 (default)
• grade = 0 (default)
• Optical size = 24px (second from left)

Here is how:

• set these settings on the right
• search for an icon (e.g. info)
• click on the icon on the left
• click on the SVG download button
• open the file in a text editor
• copy the <svg> information
• replace in *Icon.svelte file
• Please add comment (like at the top of MoreVertIcon.svelte) to document the source and the process ... we will forget)

Question:

• Do we need the class={_class} to work correctly?

Also:

• Change the icon size of the more-items in Sidebar.svelte to be 24x24.
