PR Summary

• Enhanced Compatibility
  This update includes a new feature that allows our software to support the latest version (2.0) of the psr/http-message tool, which we use for handling HTTP messages in our applications. This change will allow us to benefit from all the latest features and improvements in psr/http-message.

• Updated Dependencies in Composer.json
  We've made changes to our project's composer.json file (which defines what other tools our project needs to work). The specific change here is that our software can now work with either version 1.0 or version 2.0 of psr/http-message. This flexibility means that our application is compatible with more environments and setups, enhancing its overall versatility.
