How can I install centreon/centreon?

My website is built with Drupal 8.3.2. I want to update to to Drupal 8.9.x, but I don’t want to move to Drupal 9.x. I ran the following command.

composer update drupal/core-recommended:8.9 --with-dependencies

I am getting these errors. The site uses PHP 7.3.33.

Could not load package centreon/centreon in http://repo.packagist.org: [UnexpectedValueException] Could not parse version constraint optimize-browser-configuration-dev: Invalid version string "optimize-browser-configuration-dev"

I tried to install centreon/centreon, but there is no package.

Can anybody help me with resolving this issue?

This is the content of the composer.json file used for the site.
