CT's Nextcloud, Freshrss.heimdall & mailbackup: Refractored PHP Installation

Now using external `AlpinePHPTool`  script for installing/configuring php.
This wil make upgrading PHP on existing containers automaticaly plausible/easier.

Removed php packages from alpine.yaml and moved them to CT-Files `Config/php.pkglist`
Remove PHP configurations steps from CT's init.sh and integrated them in  ` AlpinePHPTool`
Removed PHP timezone configuration files and intergradeded them in `AlpinePHPTool`
Updated
