feat: deprecate Mumbai testnet (#3521)

### Description - Removes all reference to Mumbai testnet, since it is soon being [deprecated](https://polygon.technology/blog/polygon-pos-is-cooking-the-napoli-upgrade-means-better-ux-the-mumbai-testnet-takes-a-bow) by the Polygon team - Monorepo docker tag: https://console.cloud.google.com/gcr/images/abacus-labs-dev/global/hyperlane-monorepo@sha256:d4b44359cae9c4e3bdeb6f965c59d056f7fce72c42069adc0dea038ac600785a/details?authuser=5&project=abacus-labs-dev&tab=info - Agent docker tag: https://console.cloud.google.com/gcr/images/abacus-labs-dev/global/hyperlane-agent@sha256:a578d96f7f06721d0b6cd8095d6a1fa5d22f01b59eba3320ee3b1fe34ca3c5df/details?authuser=5&project=abacus-labs-dev&tab=info ### Drive-by changes - Adds missing Testnet domains, Fuji & BSC Testnet - Fix for failing `test-rs` CI check with ``` error[E0004]: non-exhaustive patterns: `chain::KnownHyperlaneDomain::Fuji` and `chain::KnownHyperlaneDomain::BinanceSmartChainTestnet` not covered --> hyperlane-core/src/utils.rs:226:15 | 226 | match $v { | ^^ patterns `chain::KnownHyperlaneDomain::Fuji` and `chain::KnownHyperlaneDomain::BinanceSmartChainTestnet` not covered ``` ### Related issues - Dependency on #3523 - Fixes #1181 ### Backward compatibility - [x] Backwards compatible - [x] Requires docker image tags to be added post-build - [x] Requires agent artifact cleanup in cloud account: https://www.notion.so/hyperlanexyz/Runbook-83c755f2652943289cf98cd1309487a8?pvs=4#77730653a12f409dacfbd427cab545d3 ### Testing * Build success * `yarn hyperlane chains list -e testnet` does not return `mumbai` * fork.sh script success locally
