[WIP] Update cache key to include deployment Id for deployments

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

in packages/project/src/services/WatchedLambdaFunctionsService/WatchedLambdaFunctionsService.ts:59...

Let's adjust the cache key.

I'd like to include the deployment Id in the cache key, so that we have a separate cache for each deployment. This way, we can avoid potential issues with stale cache entries when we deploy new versions of our functions.

saw an example of fetching deploymentId in

        const deploymentId = coreStackOutput?.deploymentId;

saw it in packages/project/src/features/Watch/Watch.ts:230.
