Names of startup packages that are being precompiled are not being printed anymore

[jishnub]

Currently, on launching julia nightly, the output in the REPL is

$ julia +nightly
  6 dependencies successfully precompiled in 32 seconds. 16 already precompiled.
  8 dependencies successfully precompiled in 54 seconds. 12 already precompiled.
  4 dependencies successfully precompiled in 18 seconds. 10 already precompiled.

Previously, this used to print the names of the packages as well.

This is a regression caused by #55588 because of two reasons:

1. the progress bar no longer mentions the package name if it's being called on a package that is being loaded (rather than a project, like Pkg does)
2. the progress bar is being cleared after finishing

The simplest option would be to modify the report that does print to list what was being precompiled (project/package(s)) and do it in the standard styling.
