How to release new version for this gem?

[PikachuEXE]

Although #359 related but I think it's better to start a new conversation to not spam other people

As I said in #359 (comment)

The publish workflow seems to be using RUBYGEMS_API_KEY which does not require me being gem owner

So I am not sure what should be done to release this gem (just add a commit with version updated & tag it with v prefix?)
Or should I even be able to publish new versions (I have no idea what are the expectations for new collaborators here

I think we need to bump the version (see #367) and then we can run the publish workflow.
