Extend compat and bump version

[itsdfish]

Hello,

I noticed there are a lot of pull requests for CompatHelper. Would it be possible to merge those pull requests and register a new version?

Thanks!

Hmm somehow I missed these PRs. Fortunately I think all of these compat updates are for docs/tutorials, so a new release is not needed? I guess they require manual intervention though since the corresponding Manifest.toml files have to be updated as well.

No problem. It's easy to miss.

Good question. I'm not sure how that works. Maybe when StatsBase is listed under extras, it won't block new versions of StatsBase.

I'm pretty sure the package supports the latest release of StatsBase without us merging any PRs - StatsBase is not a dependency of the package and no compat entries are specified for it: https://github.com/JuliaOptimalTransport/OptimalTransport.jl/blob/master/Project.toml

Adding OT at the current version drastically downgrades a lot of other packages (JuMP 1.23 --> 0.21 so more than two years ago), there are compat bounds here that seem to be limiting and pretty blocking
