net-im/toxic: correct version string in package

net-im/toxic: correct version string in package

Upstream's first commit after the Release fixes this. This is a quick
fix that will need to be removed for the next version bump, assuming
upstream remembers to update the string before tagging a release.

No input or review was received for over two weeks, leaving me with
little choice but to push, as it works for me.

Thanks to Dennis New for reporting.
