config_filepath is incorrect

[jimburtoft]

src/fmbench/config_filepath.txt and manifest.txt Both show the config files being located in the config directory, but they are now split up under subdirectories.

This causes from fmbench.utils import * in src/fmbench/0_setup.ipynb

to fail with:

config file current -> configs/config-bedrock-claude.yml, None
