Use the OS php version, if 'php_version' is unset

[xy2z]

If php_version is not set, please use the OS php version and extensions.

So in this example php-actions/composer is using php 8.5 even though the OS is using php 8.3

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - name: Setup PHP 8.3
        uses: shivammathur/setup-php@v2
        with:
          php-version: '8.3'

      - uses: php-actions/composer@v6
...

This can be fixed by simply adding 'php_version' to the composer step - however it would be nice if it just defaulted to the OS version

      - uses: php-actions/composer@v6
        with:
          php_version: "8.3" # if this is unset - it's using the latest php version (8.5 atm)

Thank you for the report. I see how this can cause confusion.

Do you think this change could be included within the latest release, or do you think it would warrant a new release version number? I feel like it's a fix, rather than a feature, so it would make most sense to be made into a minor release of the current version number.

Good question, I guess it depends on if it has breaking changes or not

This should only affect flows that havent set a php_version already, which could already be failing (like it did for me) which means it's a fix. But it could also be agued it's a new major version, if the reverse was the case (but that's probably more unlikely)

So I think I lean more towards a minor release like you said 👍
