Allow to build with PHP 8.5

[kdambekalns]

The following need a release for PHP 8.5:

• igbinary – 3.2.17RC1 by now…
• imagick
• phpredis
• spx
• xdebug

[kdambekalns]

So far this fails to build, as Xdebug won't compile, even with the master branch.

Xdebug 3.5.0alpha2 does support PHP 8.5 (and the new path mapping feature!)

Xdebug 3.5.0alpha2 does support PHP 8.5 (and the new path mapping feature!)

But it still fails to compile…

This builds now: docker build --build-arg PHP_VERSION=8.5.0RC3 -t flownative/php:8.5.0RC3 .

Running yields:

But still missing three extension releases…

[kdambekalns]

We could already enable building this, so we (and potentially others) can use it locally for testing things!?

And then drop the use of unstable extensions as they are released, before making this available to Beach?
