docs: Update remi-release from 9 to 10, and php-fpm version to latest.

[SirObby]

Updated this for Rocky linux 10, however the current text "(note: if you are running Rocky Linux 8.x or 10.x, substitute in 8 or 10 next to the "release-" below):" may be sufficient already. I updated php-fpm aswell, as latest versions are in my opinion better, in order to avoid using potentially vulnerability-prone

Author checklist (Completed by original Author)

• Good fit for the Rocky Linux project? Title and Author Metatags inserted ?
• If applicable, steps and instructions have been tested to work
• Initial self-review to fix basic typos and grammar completed

(I don't per se know what to do with that checklist especially with the first since I am not the original author of the guide, and with the third one I didn't make any language changes, I only updated versions)

Rocky Documentation checklist (Completed by Rocky team)

• 1st Pass (Document is good fit for project and author checklist completed)
• 2nd Pass (Technical Review - check for technical correctness)
• 3rd Pass (Detailed Editorial Review and Peer Review)
• Final approval (Final Review)
