Include -browser versions in autobuilds of this library

[eldstrom]

With the latest releases, 3.2.0, 3.2.1 and 3.2.2 fabricjs is also available in a -browser specific version. We use this autobuilt npm package that you provide but would actually have better use for the browser-version since we dont use node and only run a webb-based application that uses fabricjs so it would save us some dependencies if we did not need the node-bits.

Hope that can be fixed as well :)

Hey, that's interesting to have. However I can't see any documentation for this? I only see some weird discussion about the wrong way to use semver in the PR that added the feature: fabricjs/fabric.js#5786. If I were to add it I would probably make a package called fabric-browser-with-gestures

However I am not planning on adding some weird setup to remove the optionalDependencies and publish the package. When the maintainers fix or add module options I will add it to the setup.
