Documentation improvement suggestion

[Lorem396]

Version

2.4.201

Detail

Hello,

I noticed that the documentation appears to be outdated. Specifically, the so-rule-update command no longer works with the latest version of Security Onion. When attempting to use the command, I encounter the following error messages:

Error response from daemon: No such container: so-idstools  
Error response from daemon: No such container: so-idstools  

The command is referenced on this page:

• Proxy documentation.
• Cheat sheet
• https://github.com/Security-Onion-Solutions/securityonion-docs/blob/73cbb15753a6fc331642aca63b1330c0a52ef121/nids.rst?plain=1#L546 (But not really an issue here)

Additionally, I would like to suggest an improvement to the proxy documentation. It would be helpful to include an explanation stating that the proxy setup also needs to be configured for NIDS rules. It's explained in the NIDS section but it would make sense to also put it in the proxy section:
NIDS rules source options.
