feature: implemented @current and @next iteration selection (#45)

* feature: implemented @current and @next iteration selection

To use this functionality, simply pass @current or @next as the iteration value.

+Since version 1.3.0 the iteration field also supports the following values:
+
+- @current: the current iteration
+- @next: the next iteration
+
+Both of these values are provided by the `project-beta-automations` package. The following json provides an example of how to use these values:
+
+Next iteration:
+
+```yaml
+'[{\"name\": \"Iteration\",\"type\": \"iteration\",\"value\": \"@next\"}]'
+```
+
+Current iteration:
+
+```yaml
+'[{\"name\": \"Iteration\",\"type\": \"iteration\",\"value\": \"@current\"}]'
+```
+
 ## Detailed example
 
 Since this repository is also covered by this automation, you can take a look at the definition within the [project-automation.yml](.github/workflows/project_automations.yml) file to check how it is defined here.
