gitlab_application_settings: Provider produced unexpected value for package_metadata_purl_types after apply

Bug Report: gitlab_application_settings package_metadata_purl_types inconsistent state

Problem

When applying terraform with gitlab_application_settings resource, the package_metadata_purl_types value is set successfully but provider reads back different values, causing perpetual drift.

Debug logs showing the issue

Provider produced an unexpected new value for gitlab_application_settings.instance:

• .package_metadata_purl_types[0]: was cty.NumberIntVal(2), but now cty.NumberIntVal(999)

Expected vs Actual

• Set: [2] (npm only)
• Read back: [999] (unknown)

Provider version: 18.3.0

GitLab version: 18.4.1

Implementation Guide

In the gitlabApplicationSettingsToUpdateOptions function, add a block similar to the existing ones that checks for changes to package_metadata_purl_types and adds to the options if true.

Add a new test case to resource_gitlab_application_settings_test.go that attempts to set the value of package_metadata_purl_types.
