* Stop statically compiling the FTP extension
According to the documentation of `ftp_ssl_connect()`, the limitation of
requiring a static build was lifted with PHP 7.0. Thus stop forcibly including
the FTP extension, which should be needed somewhat rarely.
Example:
root@2a4c93db4a86:/var/www/html# apt-get update -qqqqq
root@2a4c93db4a86:/var/www/html# apt-get install -yyyyqqqq libssl-dev
debconf: delaying package configuration, since apt-utils is not installed
Selecting previously unselected package libssl-dev:amd64.
(Reading database ... 13257 files and directories currently installed.)

Unpacking libssl-dev:amd64 (3.0.11-1~deb12u2) ...

root@2a4c93db4a86:/var/www/html# docker-php-ext-install ftp >/dev/null
+ strip --strip-all modules/ftp.so
root@2a4c93db4a86:/var/www/html# php -r "var_dump(function_exists('ftp_ssl_connect'));"
bool(true)
* Drop `--enable-ftp` for the next patch
The PR/change mentioned was effectively reversed by https://github.com/docker-library/php/pull/786/,
after Alpine decided to move back from libressl to openssl,
hence rendering this comment obsolete and possibly confusing.
This is pulled in automatically via `gnupg`, and moved from `Recommends` to `Depends` in 99474ad900, which has been part of `src:gnupg2` since 2.1.21-4 (and every supported version of both Debian _and_ Ubuntu have 2.2.x 😇).
* Add Alpine 3.17 variant for PHP >= 8.1
Also remove Alpine 3.15
* Remove old Alpine 3.13 reference from Dockerfile-linux.template
* Improve Alpine version matching in versions.sh
