[#234] Add version increment workflow

[hoangmirs]

• Close #234

What happened 👀

• Introduces a version bump workflow in the GitHub Actions.
• The workflow is triggered by a push to the main branch or a manual workflow dispatch.
• It compares the versions on the main and develop branches and determines the next version based on the highest version. If the version on main is greater than the version on develop, the next version will be the same as the version on main. Otherwise, it will increase the minor version
• The workflow then updates the version in the package.json file and creates a new pull request with the updated version.

Insight 📝

• The steps can be moved into a separate composite action and reused in other projects
• Before, we tried to run the workflow when merging to develop or creating the release PR. We also fetched the version from the latest release to compare, but it would be easy with getting version from the main branch

We could consider moving most of the logic to a custom action (e,g., it could be with JS) as it would make it easier to break the logic into functions (with good names). Bash style if/else is kind of confusing at times.

Agree, we'll have other separate actions to deal with each step, and combine them into a shared step later.
