[tingwl0122]

Description

Fix Arnoldi algorithm's bug by using arnoldi_project defined in dattri/projection.py

1. Motivation and Context

Now the eigenspace calculated by Arnoldi algorithm will be fixed throughout the attribution.

2. Summary of the change

• modifyIFAttributorArnoldi in dattri/algorithm/influence_function.py
• fix ruff formats in mnist examples
• modify minor designs in dattri/func/projection.py

3. What tests have been added/updated for the change?

• [x] Application test: If you wrote an example for the toolkit, this test should be added.
