Default taiko provider gives a CORS error

[bbenligiray]

When I tried to execute txes on the manager multisig, I received a CORS error from https://github.com/api3dao/chains/blob/main/chains/taiko.json#L18 (because I was calling it from my browser) and had to switch my RPC URL. I assume this also affects the market.
Maybe we should check if a provider can be used with a browser before setting it as the default one. This is not a common issue though, so we can also wait and see if it happens again. Meanwhile, the default taiko provider should be changed.

Default provider has been changed in #489. I'm closing this issue as completed.

Created #494 to track this.
