Description

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.

Contributor guide

Research direction
Study the existing implementation of hover for keyed fields in gopls and extend it to handle unkeyed literals.
