[golang/go] x/tools/gopls: hover: more informative description of embedded methods

### ROOT CAUSE The hover functionality in `gopls` does not include sufficient information about the origin of embedded methods, such as the package or interface they belong to. ### CODE FIX To enhance the hover information for embedded methods, modify the `goHover` function in `x/tools/gopls` to include the origin details.

This fix adds the origin of the method to the hover information, making it more informative for embedded methods.
