Update 11 icons in the icons package to follow contribution docs

[mattrosno]

The following icons (https://github.com/carbon-design-system/carbon-platform/tree/main/packages/icons/src/main/svg) don't conform to our icon docs (https://github.com/carbon-design-system/carbon-platform/blob/main/docs/packages-icons.md).

• codesandbox.svg
• figma.svg
• filing-cabinet.svg
• illustrator.svg
• js.svg
• medium.svg
• sketch.svg
• storybook.svg
• svelte.svg
• vue.svg
• zenhub.svg

The source Sketch file doesn't include them (contribution step 1.) They don't follow the naming convention (contribution step 3.) Most important, we have no attribution of where these icons came from (contribution step 2.)

Consider adding a naming convention for if the icon is filled (colored, not all black.)

Hey team! Please add your planning poker estimate with ZenHub @alisonjoseph @andreancardona @francinelucca

Some additional notes for stuff we need to consider based on @aubrey-oneal's findings when working with exported Figma icons:

• Icons exported from Figma appear to always have width and height dimensions, which prevents them from getting resized as needed in the web app. As a workaround, we are hand-removing the width/height from the svg source, but this should be addressed automatically via the carbon-platform/icons workspace build process and organizational conventions which indicate what icons should be allowed to be resized and which should not (or maybe they all get the width/height removed?)
• The MDX currently has an MdxIcon component which we have to hand-update each time a new icon is to be allowed by that component. This could be handled differently by instead having the icons package export this component, or even combining this package with the mdx-components package to provide a single way to work with icons that are renderable via mdx on the platform.
