Import with_logger/current_logger on Julia 1.11+

[omus]

Allows dependent packages to consistently useScopedValues.with_logger as described in the README. Without this change users would need to rely on conditional imports like this:

if isdefined(Base, :ScopedValues)
    using Logging: with_logger
else
    using ScopedValues: with_logger
end
