Issue: x/tools/gopls: Code completion in gopls is not working, unable to find the packages to import
Labels: gopls,Tools,ToolProposal

#### What did you do?

I have enabled gopls in Neovim through configuring lspconfig. When I am working in a new project and type `http`, gopls does not provide code completion suggestions for `net/http`. And this issue is not limited to the `http` module, it affects all modules.

I have noticed that when I manually add import `net/http` to the import block, the code completion starts to work properly, and it also begins to suggest other modules correctly.

I guess that maybe gopls only indexes the modules in the import block and does not index the standard library or the modules listed in go.mod by default. I believe this is not the expected behavior. I think indexing the standard library and the modules in go.mod should be considered an expected behavior.

#### What did you expect to see?

Neovim should provide suggestions for packages that have not yet been imported, such as directly using `http` in a new project as I mentioned earlier.

#### What did you see instead?

Neovim does not suggest packages that have not yet been imported.
