Promote develop/1.0 to preview/1.0 (#210)

`gh release create` requires the tag to exist on the remote — creating
it locally with `git tag` is not sufficient. The job was failing every
time with:

```
tag 1.0.69.11 exists locally but has not been pushed to petesramek/polyline-algorithm-csharp,
please push it before continuing or specify the `--target` flag to create a new tag
```

## Change

- **`.github/actions/github/create-release/action.yml`** — push the
annotated tag to `origin` immediately after creating it, before invoking
`gh release create`

```diff
     run: |
       git tag -a ${{ inputs.release-version }} -m "${{ inputs.release-version }}"
+      git push origin ${{ inputs.release-version }}
```
