fix: Remove coingecko-api-v3 library and de-dupe fetching utils (#4837)
### Description - Remove coingecko-api-v3 lib which is unnecessary and breaks bundling - Remove `getCoingeckoTokenPrices` function which is redundant with `CoinGeckoTokenPriceGetter` - Simplify `CoinGeckoTokenPriceGetter` and remove need for Mock class Related: https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/4787 See discussion here: https://discord.com/channels/935678348330434570/1304125818817220653 ### Drive-by changes - Fix bundling issue with Storybook in widgets lib ### Backward compatibility No ### Testing Rewrote unit tests and tested Storybooktrevor/disable-rarichain-rpc
