cannot declare interface Stringable, because the name is already in use

Because this module requires symfony/polyfill-php80 there is a conflict with the core which also requires same. This causes errors like title.

The problem is that often such dependencies are transitive.
In this example:

media-module -> james-heinrich/getid3 -> php-http/cache-plugin -> symfony/polyfill-php80

One solution would be to simply delete the contents from the module's vendor dir before it is released.
