Feature Request

I would like to be able to set HTML attributes on GoBackButton and GoForwardButton like class or styles.

Can I take this? I am new to contributing to dioxus but would love to give this a shot.

@prasantadh Sure, go for it! I've previously looked a bit into roughly how to implement this and hopefully I should be able to help in case you get stuck.
