ci: add action to check for conventional commit messages (#281)

adhering to the [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) format is vital to make our automatic release process with [release please](https://www.npmjs.com/package/release-please/v/11.14.2) work.

- Automatically generating CHANGELOGs.
- Automatically determining a semantic version bump (based on the types of commits landed).
- Communicating the nature of changes to teammates, the public, and other stakeholders.
- Triggering build and publish processes.
- Making it easier for people to contribute to our projects, by allowing them to explore a more structured commit history.

I will make this action a mandatory one. To follow the conventional commit
format you only have to begin your commit message with:

```md
<type>[optional scope]: <description>

[optional body]

[optional footer(s)]
```

where `<type>` is one of:

```js
[
    "feat",
    "fix",
    "docs",
    "style",
    "refactor",
    "test",
    "build",
    "perf",
    "ci",
    "chore",
    "revert",
    "merge",
    "wip",
]
```

1. fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning).
2. feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning).
3. BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.

It is also possible to have multiple fixes and features in one commit message.
Please consult the [conventional commits doc](https://www.conventionalcommits.org/en/v1.0.0/)
