docker: invalid reference format: repository name must be lowercase.

For the past few days we have been experiencing the error docker: invalid reference format: repository name must be lowercase. when using php-actions/composer@master. Changing to @v6 resolves the issue.

I tracked the issue out of the action itself and off to https://raw.githubusercontent.com/php-actions/php-build/v2.2.0/php-build.bash and then got a headache looking through the shell script.

My step:

- uses: php-actions/composer@master
  with:
    php_version: 8.2
    php_extensions: sockets
    dev: yes

Action output:

Run php-actions/composer@master

    dev: yes
    version: latest

Thank you for highlighting this. I can't imagine what the issue is off the top of my head, but seeing as it's quite reproducable it shouldn't take long to figure out a solution.
