[slope] update to 6.3.0

[jolars]

Update slope to v6.2.0: https://github.com/jolars/libslope/releases/tag/v6.2.0

I don't really understand these errors:

ERROR: LoadError: MethodError: no method matching haskey(::Vector{Base.UUID}, ::String)
The function `haskey` exists, but no method is defined for this combination of argument types.

[jolars]

Almost all failures are on Julia >= 1.11.

This is a known issue. Here is a possible workaround, borrowed from PR #12820:

# Workaround for haskey bug in Julia 1.12: Empty weakdeps from Pkg stdlib
# The bug is triggered when a stdlib (like Pkg) has weakdeps and gets resolved
# as part of the dependency graph. The code tries to call haskey(p.deps, name)
# where p.deps is a Vector{UUID} but the code expects a Dict.
# By emptying weakdeps, we avoid the buggy code path in Pkg.Operations.fixups_from_projectfile!
uuidpkg = Base.UUID("44cfe95a-1eb2-52ea-b672-e2afdf69b78f")
for v in [v"1.12.0", v"1.13.0"]
    stdlibs = Pkg.Types.get_last_stdlibs(v)
    if haskey(stdlibs, uuidpkg)
        empty!(stdlibs[uuidpkg].weakdeps)
    end
end

Thanks @fingolfin ! I'm trying now.

Okay, progress! Now only Julia 1.14 fails, with a new message:

Okay, it works! Please don't merge yet, I am going to try to update to the newest version of the library first

[jolars]

Okay, this is good to go now (from my side at least)!

[fingolfin]

Since Julia 1.12.4 is out know, maybe we should switch Yggdrasil to use it and then try to get rid of the workaround/hack here... @giordano ?

[jolars]

👋 Just a friendly reminder about this PR. Is there any chance this could be merged?

[fingolfin]

Can you try removing this again now? It should not be necessary anymore

[jolars]

Thanks @fingolfin !
