First cut at RI state calculator

## Description - New .html page for the RI calculator - Card-based presentation of incentives, rather than the table like in the IRA calculator. This follows the initial designs. No utility incentives yet, only state + federal. Utility selection will come in a followup. If you enter a non-RI zip code, the API gives the error "we don't yet have state-level coverage in <state>". This isn't exactly what we want -- it should say "that zip/address is not in Rhode Island". This will require an API change to add a "state" parameter. ## Test Plan Enter a RI zip code and make sure that RI incentives come up. **Note** this new page will not be available in the Vercel preview. I haven't configured the Parcel build to include `rhode-island.html` yet, because I don't want the page to be publicly available when this lands. ## Next Steps Follow-up PRs that add the utility and project fields.
