`@edit` doesn't work on `Compiler` in 1.12

[oscardssmith]

@edit Base.Compiler.tmeet(Int, Float64) looks for Compiler in usr/share/julia/usr/share/julia/Compiler rather than usr/share/julia/Compiler. This presumably broke when we excised Compiler from Core.

can you explain me about the bug @oscardssmith

[oscardssmith]

#56409 moved Compiler out of Core and into a stdlib like status, but something in how @edit works when editing Compiler broke with this move.

looks for Compiler in usr/share/julia/usr/share/julia/Compiler rather than usr/share/julia/Compiler

To me it seems more like the path is a relative path:

julia> f = (@which Base.Compiler.tmeet(Int, Float64)).file
Symbol("../usr/share/julia/Compiler/src/abstractlattice.jl")

while for other stdlibs:

julia> using UUIDs

julia> @which uuid4()
uuid4()
     @ UUIDs ~/.julia/juliaup/julia-nightly/share/julia/stdlib/v1.12/UUIDs/src/UUIDs.jl:116

Maybe this function needs updating:

julia/base/methodshow.jl
