FRP: Add "Prisma Vaults" sort filter

[dudesahn]

Proposal

• Add a new sorting filter (tag?) for Prisma Vaults
• Could find them by, for a given vault:
  • pull all attached strategies
  • if ANY strategy name contains "prisma" then it's a prisma vault
• can view via https://yearn.fi/vaults?categories=prisma
• Ideally, these vaults would also show up in search for "Prisma"
• Currently we have 7 Prisma vaults (for testing to make sure you get them all 😎)

Solve

Allows users to more easily search and sort for Yearn's Prisma vaults (vaults that farm Prisma rewards using Yearn's vePRISMA boost). Since most of these vaults do not currently have PRISMA as a token in the LP, they do not all show up when searching "Prisma".

Thoughts
