Support custom options to cargo release

[mmagician]

I'd like to be able to use cargo release with the --dependent-version fix option.

Context: When releasing all crates from a workspace at once (related to #53), there are some dependencies between the crates (and circular dev-dependencies, with this workaround for now), and bumping dependent versions breaks the build. Concrete example: arkworks-rs/algebra.

I understand that not all options can be supported, else the action would break, but I think this is an option that shouldn't affect the result.

I'd definitely accept a PR for an option to change the value of --dependent-version!
