Pipeline is broken [#3586706]

Problem/Motivation

The pipeline is broken.

Running the pipeline causes the following Composer error:

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires drupal/core-recommended 11.3.5 -> satisfiable by drupal/core-recommended[11.3.5].
- Root composer.json requires drupal/php_ffmpeg 1.x-dev -> satisfiable by drupal/php_ffmpeg[1.x-dev (alias of dev-1.x)].
- drupal/core-recommended 11.3.5 requires drupal/core 11.3.5 -> satisfiable by drupal/core[11.3.5].
- drupal/php_ffmpeg dev-1.x requires drupal/core ^9.1 || ^10 -> satisfiable by drupal/core[9.1.x-dev, ..., 10.6.x-dev].
- You can only install one version of a package, so only one of these can be installed: drupal/core [9.x, 10.x, 11.x].

Steps to reproduce

Run the CI pipeline.

Proposed resolution

Update php_ffmpeg to support Drupal 11 by adding compatibility for Drupal core 11.x (adjusting the version constraints accordingly).
