Max supported photoswipe library version is too low

I removed the max version entirely, as I don't think any newer Version will drop compatibility with this module if it isn't a major release (like photoswipe 6). Alternatively, we could also change the max version to 5.9.9, @Anybody should decide.

Please review!

Totally agree, I never liked that max version thing, at least for non-major releases.

What would make sense to me is to use <=6 for max version to clarify we only support 5.x?

Let's just keep it this way for now. We can introduce that, if we run into issues ... presumably there won't be PS6 soon ;)
