Fix Virtual Machine v2 and Virtual Machines v2 Data Sources: Correct memorySizeBytes Attribute

[akli-ime]

This PR addresses an issue with the memorySizeBytes attribute in both the Virtual Machine v2 and Virtual Machines v2 data sources. The attribute was previously incorrectly fetched. This fix ensures the memorySizeBytes is properly retrieved and correctly handled.

The value of memory_size_bytes is equal to zero because the provider is looking for memory_size_bytes (with an underscore), while the Nutanix V4 API returns memorySizeBytes.

Using Nutanix API

I found the cause of the issue. It was the Terraform version (1.10.0). Updating to version 1.10.5 resolved the problem.
