[One Discover] Handle missing privileges for creating alerts and SLOs

[gbamparop]

📓 Summary

When users lack certain privileges that would enable them to create alerts and SLOs, the action menu item for alerts is still displayed in Discover's header, however, submitting the creation forms in the flyouts results in errors.

When the Management -> Rules Settings -> All Kibana privilege is not set, the action menu item for alerts is not displayed but this privilege is not enough to create the rules provided.

The required privileges should also be documented and referenced from the relevant product docs.

@isaclfreire as spoken offline, this might be a good time to also integrate these ux scenarios with the new selector design.

Updated the description as the data source selector is removed with Logs Explorer, but handling missing privileges for alerts and SLOs is still applicable in Discover.
