Fix ollama windows installer (#1894)

* Fix Windows filename issue in scheduled support bundles

* Fix: Close temp file before executing Ollama installer on Windows

Windows requires files to be closed before they can be executed. This fix
ensures the temporary installer file is properly closed before attempting
to run it, preventing file access errors on Windows systems.
