fix: remove on_disk settings from Qdrant configuration to fix Windows 11 crash

The on_disk: true settings added in v3.26.1 were causing the extension host to crash
on Windows 11 with VS Code Insiders. This commit removes these settings from both
the vector store implementation and its tests.

Fixes #7482
