fix: benchmarking config template

[josecelano]

Fix benchmarking config template:

• Missing [core.tracker_policy] section. The configuration was changed.
• Missing database config. Needed when the default DB folder does not exist. With this config, a storage folder is not needed. We are not using DB, which requires DB for benchmarking.
