fix(compass-crud): show error for bulk operations COMPASS-8529

[paula-stacho]

Description

We didn't show any error info in the bulk delete and bulk update toasts. This was particularly confusing in case of network errors (as reported in COMPASS-8529).

We already show error messages with other operations (e.g. when find fails), so I am adding the message in these toasts. Additionally, we use a different description for network errors.

Example - operation timeout (low maxTimeMS)

Example - lost connection timeout
