[BUG] Delete All PITs returns 404 if no PITs are present

[nhtruong]

Describe the bug
When hitting DELETE /_search/point_in_time/_all to delete all PITs, the server will return a 404 error if no PITs are present.

To Reproduce
Execute DELETE /_search/point_in_time/_all when there are not PITs.
Easiest way to do this is hitting that endpoint twice in a row.

Expected behavior
The server returns 200 StatusCode with { "pits": [] } as the body when there are no PITs to delete.

Plugins
None

Host/Environment (please complete the following information):

• OS: Mac
• Version: OpenSearch 2.4.x

Thanks @nhtruong for reporting this. 200 StatusCode with { "pits": [] } is make sense for me.
Would you mind to submit PR with your proposal?
