[BUG] unicodeplots() gives LoadError

[Socob]

Details

Using unicodeplots() results in a LoadError, and subsequent plotting doesn’t work. Perhaps related to #4648/JuliaPlots/UnicodePlots.jl#332?

Oh yes, it's just that it needs a new version of Plots tagged.

#4648 fixes this.

We usually wait for a few PRs to go in the master branch before tagging a new version, but given the nature of the issue (making the backend non-functional) I'll try to release a new version today.

A new version will be out in a moment: JuliaRegistries/General#77404.
