Get prices provider configuration from Safe Config Service

[hectorgomezv]

Summary

This PR changes the source for the Prices Provider (currently CoinGecko) configuration from the CGW hardcoded (configuration.ts) one, by the Chain entity coming from the Safe Config Service.

In this first iteration, the hardcoded configuration (configuration.ts) is kept as a fallback. If the Prices Provider configuration data is not present in the Config Service response, then the fallback data is used.

For more context see the Config Service PR: https://github.com/safe-global/safe-config-service/pull/1124

Changes

• Changes the primary source for both nativeCoinId and chainName properties in CoingeckoApi to the Chain entity passed.
• Changes several interfaces accordingly to pass the whole Chain entity (holding the needed configuration) instead of passing the chainId property only.
• Adds the prices provider configuration fields to the Chain entity/schema.
• Modifies the affected test classes.
