feat: build pixelfed for php 8.4 (#106)

* Copy PHP config into 8.4 folders
* Templateize the FPM / Procfile to be PHP version agnostic
* Increase CI PHP memory limit to 256M to work around
pixelfed/pixelfed#5540
* Update docs to reflect 8.4 is available

Not changing default to 8.4 yet, as it need some real life testing first
