Remove "or later"

I am not a lawyer, so take this with a grain of salt, but I don't see how you can state "or later" without including the license of the later version of the GPL. Probably makes sense to just omit this and when the GPL does create a newer version, add the license file and license it under that one as well as this one.

For example, the AGPL might be considered "later" but it's not clear to me that you want to license it under that license. Best to be explicit and specific. :smile:
