refactor: repository and source structure (PR #25)

## Feat

Totally refactored (simpler source structure)

* feat: new Docker image (more secure and light weight. Debian -> Alpine)
* feat: codeQL-analysis.yml
* feat: auto mod updater (auto PR on go.mod update)
* feat: auto merge on go.mod update only (via mergify)
* feat: include go.sum

## Fix

* fix: #23 bad indentation
* fix: golangci-lint warnings
* fix: use latest goclangci-lint for lint check
* fix: mergify.yml (deprecated "strict" config)
* fix: redundant checks (only on push to main)
* fix: remove bin directory

## Chore

* Update platform-test.yaml
* Update golangci-lint.yaml
* Update version-tests.yaml

-It includes most of the necessary packages and tools for developing Golang app. Aiming to provide the same environment to develop the app.
+It includes:
+
+- Latest [Alpine-based container image](https://github.com/KEINOS/VSCode-Dev-Container-Go/pkgs/container/vscode-dev-container-go) with vulnerability and security scan via Synk, Dockle and Trivy.
+- Latest Go version.
+- Common packages and tools for developing Golang app and shell scripts.
+  - [Installed tools and Go modules](https://github.com/KEINOS/VSCode-Dev-Container-Go/blob/main/image_info.txt) | VSCode-Dev-Container-Go | KEINOS @ GitHub
+- Weekly updated.
 
 ## Developing Online
 
-If GitHub detects this directory (`.devcontainer`) in the repo, then you will be able to develop online via [GitHub Codespaces](https://github.com/features/codespaces).
+Just press the `.`(dot) key on GitHub and you should be redirected to [GitHub Codespaces](https://github.com/features/codespaces). (You may need to register to use Codesspaces)
 
 ## VS Code + Docker User
 
 The container contains VS Code Server as well. If you already have installed the "[Remote - Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)" extension, then press "<kbd>F1</kbd>" and select "`Remote-Containers: Open in Container`".
 
 After a while, you'll get most of the environment needed to develop and debug.
