Added GitHub Actions Release flow

[dominiquekleeven]

Closes #10

This PR introduces the following GitHub Actions workflows:

docker-image.yml

• Triggered when a commit is pushed to main or when a release is published
• Triggers ci.yml to run code quality checks
• Sets the image tag:
  • If triggered by a release -> tags will be the release version and latest
  • Otherwise -> falls back to develop
• Builds and publishes the Docker image for multiple platforms (amd64, arm64)

release.yml

based on the release.yml from the main repository

• Triggered via manual workflow dispatch
• Accepts inputs for the version increment (major, minor, patch) or a version override
• Uses bump-my-version to handle version management:
  • Reads the current version from pyproject.toml
  • Calculates and updates the new version
  • Automatically commits the version change with the message chore: bump version to {version}. Python projects/packages expect the version to be explicitly maintained in pyproject.toml, so this automates that
  • Creates a git tag for the new version
• Pushes the commit and tag to the main branch
• Creates a GitHub release with auto-generated release notes
• The release event will trigger the docker-image.yml flow

I've also reset the version back to the original 0.1.0, which will be incremented once releases are made.

Additionally, this PR includes minor changes to ci.yml, primarily aimed at improving readability/formatting, and adds a release.yml file to the root of the .github folder, which is used to generate the release notes.

I've also set up the secrets for the GitHub repository and created the repository on DockerHub.

Code looks good to me, just a few minor changes.

[denniskuijs]

Small cosmetic change: replace double quotes with single quotes.

[dominiquekleeven]

Changed it to single quotes.

Seems they were accidentally changed to double quotes due to the formatter I use.

[denniskuijs]

Maybe only include the platforms that are necessary: linux/amd64,linux/arm64

[dominiquekleeven]

Good catch, I've changed it so it specifies the platforms now.
