Package drupal/photoswipe's dist key should be specified

@trickfun thanks for pointing this out, could you please compare the actual composer.json to https://getcomposer.org/doc/05-repositories.md

Mhm I can't see the mistake. Anyone? (Just corrected broken formatting meanwhile)

Which composer.json? project composer or module one?

The one in the module.

But yes, I get the same error when using composer require drupal/photoswipe:^5
Let's try to tag a new release without any change, perhaps the Drupal CI build didn't work?

composer require drupal/photoswipe:5.x-dev@dev works without the error.

@trickfun that's it! Just tagging a new release without any change fixed it.
Let's still fix the code style issue in the composer.json.
