security/zeek: Update to 7.0.4

https://github.com/zeek/zeek/releases/tag/v7.0.4

This release fixes the following bugs:

• The community-id-logging.zeek policy script was used to set c$conn$community_id during new_connection() rather than connection_state_remove(), allowing other scripts to reuse its value early.
• The input framework will no longer get stuck and use 100% of the CPU when encountering lines not immediately terminated by a new line.
• The Modbus analyzer added some additional protocol checks and should no longer over-match on traffic that's not specifically on port 502.
• ZeekJS was updated to version v0.13.2, which brings support for newer versions of Node.js and a fix for a segfault when running under Alpine.
• A minor bug was fixed in the detect-sqli policy script to handle spaces being encoded as plus signs.
