feat(vendors): add EY starlight

[rymnc]

Adding a Vendor/Protocol

Protocol Name: Starlight

Company: EY

Brief Description:

solidity transpiler for private on-chain state

Documentation Link: https://github.com/EYBlockchain/starlight/tree/master/doc

Status:

unclear, testnet to err on the side of caution

Checklist

• I've used the vendor template format (vendors/_template.md)
• All technical info is accurate
• The vendor I'm adding is within the scope

Additional Notes

[oskarth]

Did we ask EY to add this themselves? Ideally vendors add on their own (accuracy, involvement, feedback loops), but if they don't we can do it for them. Maybe can ask them to sanity check accuracy and contribute PR for tweaks too?

We already have a card for EY.
We can change the name of that one to ey.md and reference both nighfall and startight there.

its not clear if vendor should mention just the company name or the product. the others mention them interchangeably, whats the pattern here?
