Comments on the "Number of open files" page

Hi,
I have some comments/suggestions for the "Number of open files" page.

1. There are currently two pages with similar titles:

   • https://neo4j.com/developer/kb/number-of-open-files/
   • https://neo4j.com/developer/kb/number-of-open-files-on-linux/

   The first one is deprecated and no longer works on RHEL-like distributions. Ideally, it should contain a pointer to the new one.

   The second page states that it's applicable for versions 3.{3,4,5} but it applies to 4.x as well.

2. On both pages, the configuration for Debian systems seems incorrect. It suggests adding the following to `/etc/security/limits.conf.

   neo4j  soft  nofile  40000
   neo4j  hard  nofile  40000
   

   However, the syntax in the /etc/security/limits.conf file states that the user name should come first, so for most users, neo4j should be something else. A wildcard (*) could also work. (See a Stack Overflow answer on the topic).

3. The characters denoting smaller than, <=, are interpreted as a ligature and are rendered as a leftwards arrow, ⇐. Maybe it's easiest to just use the Unicode ≤ instead.

Review the two linked KB pages, especially the deprecated Number of open files page and the Linux variant. Verify the Neo4j version coverage, Debian limits.conf example, and rendering of <=, then update the documentation so the old page points to the new one and both pages show correct, readable guidance.
