Skip_existing not seen as a valid input

[or4dx]

I get the error below when I try to use skip_existing as an input as shown in the inputs here

Release Unexpected input(s) 'skip_existing', valid inputs are ['version', 'config', 'charts_dir', 'install_dir', 'install_only', 'skip_packaging']

Would be great to have it as part of the github actions workflow inputs
