[cli] Fix start hermes debugger crash when starting with --dev-client

[Kudo]

Why

a regression from #19872 which starting dev-server with --dev-client parameter and pressing j to launch hermes debugger. the cli will crash with TypeError: Only HTTP(S) protocols are supported.

How

with --dev-client parameter, the returned getNativeRuntimeUrl will not be scheme://expo-development-client/?url=.... since the url is quite different between expo-go and dev builds. this pr adds a getJsInspectorBaseUrl specific for the inspector server.

• why not use getDevServerUrl
getDevServerUrl will return http://localhost by default which breaks on windows. this is what [cli][dev-server] Fix hermes debugger error on windows and linux #19872 originally trying to address.
• why not use getExpoGoUrl
getExpoGoUrl is a protected method in the server. even though we could access the internal property by server['getExpoGoUrl']().replace(/^exp:\/\//, 'http://'). that is not clear and not having a typescript typing in BundlerDevServer.

Test Plan

• ✅ start server with npx expo start and press j
• ✅ start server with npx expo start --dev-client and press j

Unit Test

 PASS   @expo/cli  src/start/server/__tests__/BundlerDevServer-test.ts
  getJsInspectorBaseUrl
    ✓ should return http based url
    ✓ should return tunnel url
    ✓ should throw error for unsupported bundler
