[CMP-1299] remove skip_packaging and skip_existing options (#19)

🐛 fix(release-helm-chart/action.yml): change packages_with_index value to string 'true'
The skip_packaging and skip_existing options were removed as they were not necessary for the Helm chart release process. The packages_with_index value was changed from boolean true to string 'true' to match the expected input type, fixing a type mismatch issue.
