SPIKE: Research Bit and other component library-associated tools

[BCerki]

Bit is a tool for making components (both front- and back-end). Features:

• easy set-up
• good versioning and dependency support (component library currently uses lerna but not to full monorepo potential)
• can grab components from different libraries
• relatively easy deploy process
• docs can include figma/designs
• looks like good support for base components and other components build off them
• does the back-end component thing mean we could use Bit for everything in the toolkit? Eg testing helpers, rjsf themes, etc.?
• can use any stack

Cons:

• slow to load new changes
• users have to do additional setup to import components: npm config set @bit:registry https://node.bit.dev
• doesn't reduce refactoring--we could bring in the components as is but the need for customization/flexibility means we're still going to need a component in every theme
