x/tools/gopls: hover over unkeyed field should show field info

[findleyr]

When hovering over the name of a field in a composite literal, we show info about that field.

But when hovering over a value in an unkeyed literal, we show nothing. If anything, field information would be more useful in an unkeyed literal! I recently bumped into this while working in the middle of a large table driven test.

This should be easy to add.

See https://go.dev/cl/631796 for a rough sketch. (I have not claimed this issue as my own.)

Hi, I'm interested in working on this issue. I've already implemented something similar for personal use. Is this still available? I'd be happy to take it on.
