feat: added win365 OIB for terraform

[ShocOne]

As promised (later than planned) please find a terraform implementation of OIB for w365.

The configuration was generated from deploying the OIB into intune then using a exporter script to generated well formed hcl, compatiable with the tf provider. If curious the script used can be found here

The hcl requires a tf provider to function and utilises this - https://registry.terraform.io/providers/deploymenttheory/microsoft365/latest . Which is a community provider (open source) that i currently maintain.
