Remove Gopls from setup in ".devcontainer" since it's now enabled in VS Code by default.

TL; DR

Remove Gopls form the Dockerfile for .devcontainer

Hello-Cobra/.devcontainer/Dockerfile

Lines 62 to 65 in 81a3c24

TS; DR

As of Go for VS Code v0.22.0, the VS Code extension will enable Gopls by default.

It still works as is now, and we need to concern the side effects to "Codespaces". But why not let the VS Code do it for us?

• "Enable gopls by default" | VSCode Go | Golang @ GitHub

Here's the list of tools that will be installed by default when the extension gets installed.

May not be needed to remove

I confirm that installing the Go extension of VSCode will activate gopls. But the version of gopls in the base image mcr.microsoft.com/vscode/devcontainers/go of the container is v0.6.4. Which is an older version.

So leaving as is and let go get -u -v update the gopls package seems to be fine.
