[catalog-backend-module-okta] Add feature to enable or disable prune groups from Okta

[SmajlovicA]

Hi team,

We are using your module to ingest users and groups from Okta, and it works great. I noticed some groups not get ingested because they are empty and then pruned before come to Backstage catalog. Wondering if is posible to make this in app-config.yaml ability to disable or enable so that we can choose if we want to prune Groups or we want to have them empty in Catalog.

I didn't check in details but I see here there is boolean for true and false:

roadie-backstage-plugins/plugins/backend/catalog-backend-module-okta/src/providers/OktaOrgEntityProvider.ts

Line 247 in fae5f18

pruneEmptyMembers: true,

Feature Suggestion

Ability in Okta Org provider to enable or disable prune Groups in Backstage catalog.

Possible Implementation

Add to use app-config.yaml to enable or disable pruning Groups.

Context

To ingest Groups empty so we can have good system model that shows ownership of services and when groups are empty then in Catalog is not showing who is owner.
