feat: remove reporting to file for detecting secrets jobs (#17)

Remove report flags and thus reporting to a file for
`detect_secrets_git` and `detect_secrets_dir` jobs. Currently, there is
not much use for such outputs, and a more systematic approach to reporting
is needed across all jobs in the future.
