feat: support for NetBox v4.4

[mfiedorowicz]

This pull request updates the plugin utilities for the NetBox Diode plugin to support new features and improve data handling. The most significant changes are the addition of support for parent relationships in platforms, updates to supported fields, and improvements to data transformation logic.

Platform relationship and supported fields

• Added support for a parent reference in the dcim.platform object, allowing platforms to have hierarchical relationships.
• Updated the set of supported fields for dcim.platform to include comments and parent, enabling more comprehensive data ingestion and management.

Data transformation improvements

• Changed the transformation functions for validation_maximum and validation_minimum fields to use transform_float_to_decimal for more accurate decimal handling, instead of converting to integers.

Documentation and metadata

• Updated the compatibility matrix in README.md to include support for NetBox version >= 4.4.0 with plugin version 1.4.0.
• Updated the generated code timestamp in plugin_utils.py for better traceability.
