[Dashboard] Make GPU name tooltip appear when hovering over entire GPU entry

[architkulkarni]

Why are these changes needed?

Previously the GPU name would only appear when hovering over the slot name (the part that says [0]).

This PR makes it appear also when hovering over the rest of the entry (the utilization bar). This is consistent with how the GRAM entry is currently displayed.

Related issue number

Closes #42208

Context copied from the linked issue:

Actually, for the GPU column, the tooltip currently appears, but only if you hover over the "[0]" part, not over the utilization bar.

For the GRAM column, the tooltip appears if you hover over the "[0]" part or the utilization bar.

So I think we just need to make sure that the tooltip appears when hovering over the utilization bar in the GPU column.

@alanwguo how would you recommend testing this part (manually or otherwise)?

One way is to let this PR build a ray wheel and install it as a cluster env to use on Anyscale and launch a machine with a GPU.

Alternatively, you can test with a kube-ray cluster with a GPU node?
