EZP-23437: Update Apache cluster rewrite rules

- Update Apache rewrite rules for apache for 5.4 cluster change
- Also re add nginx 5.3 config as doc is currently wrong given pointing directly to it (so with this it can at least continue to do that)
Well... it's ezjscore and texttoimage, which aren't relevant in the new stack. Even if the files may be here, it makes no sense to change it. Still a legacy feature.
