Providers: ANKR and dRPC don't load #5
Description
From the provider's page, after clicking on ANKR and dRPC, there's an error and the site displays a blank page.
I investigated a little, and it seems to be because both providers register support for chain ID 280 in providers.json. 280 isn't registered as a chain id in chains.ts:getChainById, so when ProviderChain.vue calls getChainById(280) in chainOptions, chain is undefined, which eventually causes a crash and failure to load the page.
