.github/workflows: Add GitHub Release title to workflow (#312)

Reference: https://github.com/hashicorp/ghaction-terraform-provider-release/issues/44

```console
$ gh release create --help
Create a new GitHub Release for a repository.

A list of asset files may be given to upload to the new release. To define a
display label for an asset, append text starting with `#` after the file name.

If a matching git tag does not yet exist, one will automatically get created
from the latest state of the default branch.
Use `--target` to point to a different branch or commit for the automatic tag creation.
Use `--verify-tag` to abort the release if the tag doesn't already exist.
To fetch the new tag locally after the release, do `git fetch --tags origin`.

To create a release from an annotated git tag, first create one locally with
git, push the tag to GitHub, then run this command.

When using automatically generated release notes, a release title will also be automatically
generated unless a title was explicitly passed. Additional release notes can be prepended to
automatically generated notes by using the notes parameter.

  gh release create [<tag>] [<files>...]
