commit_options doesn't work with multiple arguments

Version of the Action v4.1.2

Describe the bug commit_options option treats space separated arguments as one.

To Reproduce Use commit_options with multiple arguments like described in README. I tried both --no-verify --signoff and '--no-verify --signoff' although there should be no difference. I also tried passing a sequence:

commit_options:
  - '--no-verify'
  - '--no-verify'

but that didn't work either.

Expected behaviour Arguments to be passed individually instead of being treated as one. Either the example is wrong and a yaml list should be passed.
