Add hook config support to the infra checker

[tkporter]

Problem

Atm, the checker only supports address hooks, not hook configs.

Solution

• similar to what we do with ISMs, verify the actual onchain recovered config matches the expected config. I.e. around here, no longer skip if the hook isn't a string

  hyperlane-monorepo/typescript/sdk/src/router/HyperlaneRouterChecker.ts

  Lines 70 to 73 in fd20bb1

  	if (typeof config.hook !== 'string')
  	return this.logger.info(
  	`Hook objects not supported in router checker for HookConfig: ${config.hook}`,
  	);

• make sure the checker passes for the hook config in feat: Add FeeHook and Swell to pzEth #4974 - may require looking into commit history for the right tokenPrices.json (see my second point here feat: Add FeeHook and Swell to pzEth #4974 (comment))

Nice to Have
