ConsoleLogger not active in the REPL

[fredrikekre]

Logging.__init__ replaces the global logger: https://github.com/JuliaLang/julia/blob/1327dfec807fa00782311f02d095b8e37ea55f2a/stdlib/Logging/src/Logging.jl#L93-L95 Before #51399 this was more or less impossible to notice since Logging.__init__ was run when loading the sysimg. However, now this isn't the case anymore. This means that

1. The colorless SimpleLogger is used by default in the REPL
2. using Logging replaces the logger, which might be a logger a user has already configured

julia> @info "Where are my colors?" logtype = typeof(Base.global_logger())
┌ Info: Where are my colors?
│   logtype = Base.CoreLogging.SimpleLogger
└ @ Main REPL[1]:1

julia> using Logging

julia> @info "Thanks for the colors, but you stole my logger..." logtype = typeof(Base.global_logger())
┌ Info: Thanks for the colors, but you stole my logger...
└   logtype = ConsoleLogger

Not sure what the best fix is, but probably REPL should depend on Logging and setup the logger while the REPL initializes.

Maybe the cause of https://github.com/JuliaLang/JuliaSyntax.jl/issues/375

It's a problem before REPL for startup.jl too https://github.com/JuliaLang/julia/issues/51493

I was planning on moving ConsoleLogger to Base to fix this but it depends on StyledStrings now so that's not really possible.
