feat: Add auto_bump config

[tonthanhhung]

Add auto_bump, it's an optional config to let the action automatically increase version with conventional message. Based on the commit messages, increment the version from the -latest release.

• If the string "BREAKING CHANGE" or "major" is found anywhere in any of the commit messages or descriptions the major version will be incremented.
• If a commit message begins with the string "feat" or includes "minor" then the minor version will be increased. This works for most common commit metadata for feature additions: "feat: new API" and "feature: new API".
• All other changes will increment the patch version.

Push the bumped npm version in package.json back into the repo.
