Add frontend code for dependency list export

What does this MR do and why?

Add frontend code for dependency list export based on the APIs added as part of !106462 (merged)

Currently dependency list exporter isn't persisted and its endpoint is shared with regular fetching with the purpose of providing data to be populated by the frontend code.

Related issue: https://gitlab.com/gitlab-org/gitlab/-/issues/383060

The DB table was added as part of !104361 (merged)
The dependency_list_export model was added as part of !104363 (merged)
The workers and services were added as part of !104365 (merged) Follow-up MR with frontend code: !104369 (merged)
