Description

Problem Description

Currently the GitHub Action Check & Fix License Header adds multiple license headers to a .yaml file and right after a shebang (#!/) instead of at the start of the file. This affects currently all helm tests in */templates/tests/** that include #!/usr/bin/env bats.

Example

https://github.com/cloudoperators/greenhouse-extensions/blob/542c24d2f139ef32b6fbd6f51f12b98ab4c9c988/opentelemetry/chart/templates/tests/test-opentelemetry-config.yaml
