- first collect all pull requests and export to environment
- second take exported data and continue generation of changelogs (makes it cheaper, by only collecting PRs once)
- the rules can be used to match specified `Properties` with a `RegExp` (uses `test`) - to add them into a category
- This allows more complex changelogs to be constructed, which for example want all `OPEN` PRs in one category
- define priority on the config json from YML, followed by file, last with the default value
- Simplify code by merging configs right away
- thanks for the suggestion @dtcMLOps
- introuce capability of accessing and referencing custom placeholders of PRs in the global template
```
${{CUSTOM_PLACEHOLDER[0]}}
${{CUSTOM_PLACEHOLDER[*]}}
```
- introduce new testcase checking the custom placeholder functionality
- remove default value for configuration, to cleanly fallback to defaults
- rename gitHelper, move dir exists helper
- add reading input values group
- improve warning for configuration
- add configuration options for
- path
- configuration
- fromTag, toTag
- token
- allow to specify transformers to adjust information to a specific form
- allow to specify different templates
- speed up by limiting information to pull
- add logic to automatically resolve current
- use github actions logger
