ValueError: No closing quotation

The problem is the backslash that escapes the double quotes. The bash content that is being parsed is this one:
https://github.com/ComplianceAsCode/content/blob/fc6bdac51301debae58900bac597183cd7039620/linux_os/guide/system/logging/ensure_rsyslog_log_file_configuration/rsyslog_files_permissions/bash/shared.sh#L39

CLEANED_PATHS=$(sed -e "s/[\"')]//g; /\\/etc.*\.conf/d; /\\/dev\\//d" <<< "${FILTERED_PATHS}")

CTF identifies partially the token probably because this crazy sed command construction.

Reproducer: python3 content_test_filtering.py pr --rule --output json 7715

I don't know if we can circumvent this here or if this is a legitimate problem with the content. Either way we could catch the ValueError exception so the it doesn't crash.
