`tag-and-release`: new `on-major` value for the `draft-release` input

The `draft-release` input of the `tag-and-release` action could use a third value - `on-major`:

* when publishing a **major-release** - that is, when the major version has one of these formats:

   * `X`
   * `X.0`
   * `X.0.0`

  `draft-release` internally becomes **true**

* otherwise, `draft-release` behaves as if set to **false**
