Provide an option to disable creating a GitHub release

[kolaente]

I'd love to use this action to provide unstable / nightly builds of my app which are built based on what is currently on the main branch. These builds don't have a tag or release, artifacts are instead uploaded This is an approach which I already use for the other components of the app. It would be enough if the action supported just disabling the creation of a GitHub release and instead just "outputs" the binaries which I could then attach as build artifacts or upload to s3 or similar.

This is indeed something i'd like to add in the future, but i'd like to refactor larger parts of the action first so it will take a while.

In the meantime you could look at https://github.com/JonasKruckenberg/tauri-build or you could use no action at all (that's what i use in my own projects for example, where i also upload the artifacts to my own server)

Looks like i fixed this 3 weeks later in this pr #332. Simply omit releaseId and tagName and the action will not try to upload anything.
