fix: add depends on replicas for user creation

[g-awmalik]

This is an interim fix for this issue
Additionally, it uses the custom machine types for the postgresql examples since the shared instance was taking too long and timing out.

Thanks for the PR! 🚀
✅ Lint checks have passed.

Please do not use timeouts for this. That's not the right fix.

If there are issues with parallelism, the correct fix is to adjust the depends_on so it doesn't start until the earlier resources are done.

We should never expose timeout parameters to users.

We should do this for mysql too

[g-awmalik]

@bharathkkb - I can do that as another PR. Let's let this go through to unblock the customer for now.

@g-awmalik Can you add this for mysql and mssql? I want to get those into the release.

[g-awmalik]

@morgante - this includes the change for MySql as well. However, this module doesn't include replica setup for MSSQL yet. I can work on that but we may want to push these changes for now.
