feat(lit): Ubuntu Server bubble demo + Navigation component

[mariadias143]

Done

• First version of SSR Demo app to replicate Ubuntu Server bubble
• Navigation Lit component

Note:

• This PR aims to be a starting point for us to continue to work on this demo app. Currently I spot some weird behavior of the TieredList component in the SSR app, where the list items appear on the left half side instead of the right. Also, this component does not seem to be consuming the SiteLayout grid (it's not using subgrid). This is one of the follow ups we will need to address.

QA

• Checkout this repo and bun install
• To check SSR app, go into apps/lit/demo and run bun run build followed by bun run serve
• It should look something like the screenshots below
• In order to check the new Navigation component in storybook, go into the lit package directory and run bun storybook
