Merger puts tasks 'In-Progress' for each task type that exists parallely (MAPCO-4446)

If exists, TilesMerger pulls a task for each task type, if tasks exist then all but one are "lost" and get a status of In-Progress.

The relevant code is in the MainRunner file:
https://github.com/MapColonies/GpkgMerger/blob/653bdd5b9e4a17823d70ea03bbf751198c7944fc/MergerService/Runners/MainRunner.cs#L36-L40

phenomenon:
Once three ingestion processes are in parallel, tasks from all ingestion processes are moved to status In-Progress, although the merger does not work on them.

To Reproduce
Run multiple (at least 2) ingestion jobs with different ingestion types with existing tasks. (swap, new, update).

Actual behavior
Merger moves tasks to In-Progress although not working on them.

Expected behavior
Merger will "mark" only one task as In-Progress and work on it.

MergerService/Runners/MainRunner.cs、特に36-40行目から始め、swap、new、updateなど異なるタイプの取り込みジョブを少なくとも2つ実行して問題を再現します。複数のタスクが存在する場合に、どのタスクがIn-Progressとしてマークされるかを追跡します。処理中のタスクだけがIn-Progressとしてマークされ、他のタスクは利用可能なままであれば完了です。
