[Feature Request] Add world author to screenshot helper metadata & credit text export

[LakesGeek]

Explain in detail what your suggested feature would be used for.
Storing author info to the metadata would make it easier to go back and see who made the world in the screenshot, especially if you're looking in x years time and the world has been taken down and the wrld ID can't be used to find out

A credit text export on the screenshot metadata viewer button could write out something like "Cozy Winter World by FooBar21" and link to view the world on vrchat.com to the clipboard - Markdown would probably be ideal, for Discord posts.

Describe how it would look if it requires a UI.
Just the author info on its own wouldn't need a UI.
For the credit feature, on the existing "Screenshot metadata" window, a button "Copy credit text to clipboard" or similar could do the job. Maybe an option for a Markdown Link export.

Explain why people would want to use it.
When posting our VRChat photography to Discord servers, Instagram and the like, it's nice to give credit to be courteous to world creators and to allow other users to explore the world depicted. Currently this is quite a laborious manual task. It'd make it much easier for people to give credit if they just had a button to generate the text from the screenshot.
