Description

The "Historical limitations" section noted that --net=host ports weren't reachable from the host network namespace under RootlessKit, but didn't say this was resolved. Meanwhile, a separate troubleshooting entry on the same page still told readers to "upgrade to Docker Engine v29.5 or later" which implied that the fix might still be pending, even though v29.5 shipped months ago and the current Engine version is v29.7.2.

I confirmed the fix in the v29.5.0 release notes, under Bug fixes and enhancements: "Rootless: Properly support --net=host and localhost registries" (moby/moby#47103).

This updates the Historical limitations bullet to note the fix landed in v29.5, and rewords the troubleshooting entry so it no longer suggests current users need to upgrade. A related section on this same page ("Network is slow") was already updated for this in #25066 and this closes the remaining gap that PR left.
