Configure GitHub Codespace to launch with useful plugins preinstalled

Hugo VSCode plugins: https://gohugo.io/tools/editors/

GitHub Codespace customization resources:

• https://docs.github.com/en/codespaces/setting-up-your-project-for-codespaces/adding-a-dev-container-configuration/introduction-to-dev-containers
• https://code.visualstudio.com/docs/devcontainers/create-dev-container

As i'm working on multiple projects in different programming languages, my VSCode has way too many plugins that get in the way. Having a clean environment with only useful plugins would be great

GitLens VSCode plugin should be preinstalled

Issues with current configuration:

• theme submodules are not updated when creating a dev container
• hugo shipped with devcontainer image is not an extended version and does not work with hugo-book theme

[TheStalwart]

devcontainer image contains two versions of hugo binary:

• extended: /opt/hugo/0.112.5/hugo
• shitty: /usr/local/hugo/bin/hugo

$PATH is set to resolve to the wrong one by default

Commands to be added to devcontainer.json:

• git submodule init
• git submodule update

[TheStalwart]

Submodule update added to postCreateCommand.

After rebuild, devcontainer does not contain /opt/hugo anymore. Only shitty version installed.

Another weird issue - Hugo VSCode extension is preinstalled, but Hugo language mode is not available resulting in no proper syntax highlighting
