Duplicate include(::String) for nicer stacktraces

See #33065 (comment)

Before:

ERROR: LoadError: UndefVarError: STOP not defined
Stacktrace:
 [1] top-level scope at /home/antoine/scratch.jl:1
 [2] include at ./boot.jl:328 [inlined]
 [3] include_relative(::Module, ::String) at ./loading.jl:1105
 [4] include(::Module, ::String) at ./Base.jl:31
 [5] include(::String) at ./client.jl:432
 [6] top-level scope at REPL[2]:1
in expression starting at /home/antoine/scratch.jl:1

After:

julia> include("scratch.jl")
ERROR: LoadError: UndefVarError: STOP not defined
Stacktrace:
 [1] top-level scope at /home/antoine/scratch.jl:1
 [2] include(::String) at /home/antoine/julia-fork/base/client.jl:443
 [3] top-level scope at REPL[4]:1
in expression starting at /home/antoine/scratch.jl:1

Unfortunate to have to duplicate code but this code rarely change and it has an impactful change to the stacktrace printing so +1 from me.
