feat(infra): strongly type keyfunder config (#4093)

resolves https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/3732

- strongly type the keyfunder config
- new chains added to an environment's supported chains list must be
configured
- opens up the path to strongly type more of the env config down the
line

missing 1 chain:
