Query delimiter for automatic child process import

[solth]

Describe the bug Kitodo.Production supports encapsulating a search interface query inside an optional query delimiter character. This query delimiter was missing during hierarchical import which was fixed in #5287. It is still missing from queries for automatic child process import, though. Since there don't seem to be many cases of search interfaces that require enclosing queries in query delimiter characters and none that also allow automatic child process import, this issue can be considered low priority.

Expected behavior Query delimiters should be incorporated search interface queries for automatic child process import.
