[Site]: Some design queries

### Current State

I think the design of this [page](https://fory.apache.org/user) could be improved a lot, currently its too much simple.

### Desired State

**Description of the change you are proposing**:
Can I propose a design ?

### Would you like to fix this issue?

Yes! Please assign to me!

Start with the linked /user page and compare its current design with the attached screenshot. Before implementation, turn the general request into an agreed concrete design proposal; done should mean the proposal is accepted and the page's identified design changes are implemented.
