Include license = ... in Project.toml

[nickrobinson251]

Project.toml files can have a license = "..." entry (see JuliaRegistries/RegistryCI.jl#344 (comment)). This can be used to clarify the license in the presence on multiple licences being present in the repo (e.g. for different parts of the code)

Since we create the Project.toml and License (when those plugins are present, which they are by default), we could add this line to the Project.toml when we create it
