Qualify public, unexported bindings in REPL help

[ararslan]

Fixes #52472, which was caused by names being changed to also return public, unexported symbols in #50105. Note that this restores previous behavior. A case could be made to instead add the public, unexported bindings as suggestions with the appropriate qualification.

Not entirely sure how to test this so I'd welcome any suggestions.

I'm not sure how hard it'll be, but suggesting public but unexported names will be really helpful. This may be a separate PR though

[ararslan]

I had a go at it here in a separate commit.

Example from #52472 (screenshot rather than code copy-paste to show that highlighting is still working as expected):

Interestingly, this test fails on some platforms and works on others. 🤔 It works for me locally on macOS ARM but fails on macOS ARM CI. It also fails on Linux x86_64 but works on macOS and FreeBSD x86_64. I have not the slightest idea why that could happen.

[ararslan]

@vtjnash, any idea why this might be different across platforms?

SGTM

Looks like the sort order seems arbitrary, since the first 2 have the same name?

Part of the implementation aims to disambiguate by adjusting the edit distance so that one case is always sorted before the other but perhaps it was not implemented correctly.

[vtjnash]

I am not sure where range came from in the suggestion list, but is it possible these have the same score for TestSuggestPublic.dango and dango?

[ararslan]

Certainly possible, though if they did then I would have expected these tests to fail: https://github.com/JuliaLang/julia/pull/52524/files#diff-c16f754f85cbf6a46764e56fb6572adf5e13692d753d561d21df8a07b14b8b39R60-R65
