How can i change the author info on the plugin that i dev?

Hello,
I want to know that how can i change the author info on the plugin that i dev?
My plugin url is: https://www.ads-software.com/plugins/last-post-redirect/
As you can see in the right hand side of the page
There is a “Author” Tag.
I want to use my Gravatar and profile in there.

PS: Other plugins like https://www.ads-software.com/plugins/crayon-syntax-highlighter/ have the Gravatar and profile when i click it.

Thanks!
