Missing functionality for platform_group (Resource)

[shwetajfrog]

Is your feature request related to a problem? Please describe.

The new platform terraform provider to manage groups we noticed some missing functionality.

With the Artifactory Group Resource it has the ability to control the xray flags for the below:

policy_manager (Boolean) When this override is set, User in the group can set Xray security and compliance policies. Default value is false.
reports_manager (Boolean) When this override is set, User in the group can manage Xray Reports on any resource type. Default value is false.
watch_manager (Boolean) When this override is set, User in the group can manage Xray Watches on any resource type. Default value is false.

However the platform_group (Resource) does not seem to have the same functionality.

Describe the solution you'd like

We would need platform_group (Resource) also support attributes same as Artifactory Group Resource

Describe alternatives you've considered
None
