REPL autocompletion of `using Base.submodule` doesn't work in v1.10

[giordano]

In both Julia v1.10 and current master (b058146):

using Base.Binary<TAB>

doesn't complete to

using Base.BinaryPlatforms

anymore. It seems to apply to all Base submodules, as far as I can tell, it works without using though.

It is not public anymore:

Same problem for Base.Threads or Base.Filesystem which are public

help?> Base.Threads
  Multithreading support.

help?> Base.Filesystem
  No docstring or readme file found for public module Base.Filesystem.
