feat: build and push docker image to ghcr workflow

GitHub Actions Workflow to Build and Push Docker Image to GHCR

Description

This PR introduces a GitHub Actions workflow that automatically builds and pushes a Docker image to GitHub Container Registry (GHCR) on new version tag pushes (v*..). It includes:

1. Checkout of the repository
2. Setup of Docker Buildx
3. Authentication to GHCR
4. Extraction of the semantic version from the tag
5. Docker image build and push using GitHub Actions cache for improved performance

This automation ensures consistent, versioned Docker images are published with each release.

@ShehanChamudith Make a build workflow that runs before Build and Push to Docker. after the go build is complete, run Build and Push to Docker.

[sathirak]

@ShehanChamudith can you modify the github actions scripts so that we use two seperate scripts for build-go and docker build (example: build.yml, docker.yml). Docker build needs be be referenced like below from the build.yml and should only be run on tag releases. But build should run on PR to main and Push to main and also on tag releases

   trigger-docker-build:
     needs: [build-go]
     if: github.ref == 'refs/heads/main'
     uses: ./.github/workflows/docker.yml
     secrets: inherit

we should not build and release for cross platforms with the build.yml

we should maintain two workflows

1. build.yml for building for anything like main, prs or a tag push
2. release.yml - triggers only for a tag push

[kasvith]

shall we include following platforms? https://github.com/kasvith/hackerrank-dl/blob/6b61b6d2d7a8cc8e562360111f9a7fc9cb41023d/build/build.sh#L38

[kasvith]

you can actually copy that script here and simply run it as i did with the project

lets not compress
