chore: minor fixes in build workflow and package alignment

[castastrophe]

Description

• Add the guides folder to the storybook dependencies and include mdx assets as well
• Use a shared list of storybook dependencies called "tools" instead of redefining them in every tasks inputs
• Remove the manual ui-icons build task from the storybook build and start tasks and the site build task
• Remove the manual token build from the shared build task
• Add ui-icons to the default yarn builder and leverage the shared build task in subsequent commands
