 - `prerelease`: Mark the release as a pre-release (Default: `false`).
 - `make_latest`: Mark the release as the latest release for the repository (Default: `true`).

+- `target_commit`: Sets the commit hash or branch for the tag to be based on (Default: the default branch, usually `main`).
 - `body`: Content of the release text (Default: `""`).
 - `repo_name`: Specify the name of the GitHub repository in which the GitHub release will be created, edited, and deleted. If the repository is other than the current, it is required to create a personal access token with `repo`, `user`, `admin:repo_hook` scopes to the foreign repository and add it as a secret.
