Export-AzApiManagementApi exports int32 field max/min values as decimal numbers

### Description

APIM contains API with following openapi specification and Export-AzApiManagementApi command used to export openapi specification as yaml format. Exported specification contains decimal numbers even specification declared fields to be int32. See amount maximum and minimum properties. If openapi specification is exported via portal then numbers are correctly in int32 format. In demonstration I am using WSL2 Ubuntu 20.04.

APIM openapi specification:
```
openapi: 3.0.1

version: '1.0'
