Can't access prerelease option when building versioning strategy

[lukekarrys]

Is your feature request related to a problem? Please describe.

I would like to use the prerelease option to control the versioning strategy used. Currently this isn't possible without some workarounds since prerelease is not part of the VersioningStrategyFactoryOptions interface.

Describe the solution you'd like

Add prerelease to the VersioningStrategyFactoryOptions interface so it is available when buildVersioningStrategy is called. Then in my code I would be able to do:

ReleasePlease.registerVersioningStrategy('default', (options) => {
  if (options.prerelease) {
    return new PrereleaseVersioningStrategy(options)
  } else {
    return new DefaultVersioningStrategy(options)
  }
})

Describe alternatives you've considered

Using the versioning-strategy: "prerelease" config instead. This will work but I would like to only have to set prerelease: true and then use that flag to change the versioning strategy at runtime.

Additional context

This might be considered overloading the prerelease option, since it currently only controls whether the GitHub release is a prerelease or not. But I think making it available to the versioning strategy makes sense outside of my use case as well.

I also think that a future breaking change could set versioning-strategy: "prerelease" based on the prerelease config. But I can open a future discussion for that based on the result of this feature request.
