5.1.0 Various improvements

[shinsenter]

Version 5.1

We have updated the behavior of the environment variables used to change PHP configurations to enhance container performance:

• By default, the $PHP_* environment variables only take effect when set before starting the container.
• To dynamically change PHP configurations using $PHP_* environment variables while running commands within the container, you need to start your container with the ALLOW_RUNTIME_PHP_ENVVARS=1 environment variable.

Other updates:

• Added Docker images for PHP versions 5.6, 7.0, and 8.4-rc.
• Added Docker images for RoadRunner.
• Added Docker images for Bedrock, CakePHP 5 and Spiral.
• Improved SSL configuration for FrankenPHP containers.
• Removed warning messages from Nginx related to the HTTP2 directive.
• Fixed read/write permission issues in container directories.
• Resolved bugs in WordPress containers.
• Updated descriptions for Docker images on Docker Hub.
• Updated greeting message content upon container startup.
• Enhanced GitHub actions for building Docker images.
• Various minor improvements.
