docs: fix InMemoryTaskStore import path in experimental tasks docs

The docs import InMemoryTaskStore from the package root:

    from mcp.shared.experimental.tasks import InMemoryTaskStore

but the class is not re-exported there, so this raises ImportError. The
package __init__ explicitly directs callers to import from the submodule,
and all library code and tests use:

    from mcp.shared.experimental.tasks.in_memory_task_store import InMemoryTaskStore

Update both doc snippets (tasks.md, tasks-client.md) to the working path.
