Fix LU deprecation and improve type-stability of MatrixWorkspace

[ChrisRackauckas]

Fixes LoadError: LU{T, S}(factors::AbstractMatrix{T}, ipiv::AbstractVector{<:Integer}, info::BlasInt) where {T, S} is deprecated, use LU{T, S, typeof(ipiv)}(factors, ipiv, info) instead.` deprecation, and adds missing type parameters on lu and qr in the matrix workspace.

[ChrisRackauckas]

@oscardssmith can you help figure out what that QR error is?

[ChrisRackauckas]

julia> typeof(qr(rand(ComplexF64,5,5)))
LinearAlgebra.QRCompactWY{ComplexF64, Matrix{ComplexF64}, Matrix{ComplexF64}}

[oscardssmith]

QR and QRCompactWY are different types with different type parameters.

Can you run JuliaFormatter on the changed files?

[ChrisRackauckas]

I did but it seemed to change everything, so I'm not sure what version of the formatter you're using.

[PBrdng]

I used v1.0.56. It's fine if the formatter changes everything in those three files, as long as the format is consistent.

But I can also update the format later this week.

[ChrisRackauckas]

It changes all files, because none of them match the format.

[PBrdng]

Weird. Ok, let me run the formatter.

See #583

@PBrdng is it possible to make a bug fix release with this PR? We are having some CI errors in Catalyst due to this. Thanks!

[PBrdng]

Yes, sorry, I just initiated a release with this bug fix.

[PBrdng]

@isaacsas @ChrisRackauckas: I didn't notice it before, but is there a reason the Julia version in Project.toml has been changed from 1.8 to 1.10? This is preventing a patch release.

[ChrisRackauckas]

LU's type parameters had changed.

[PBrdng]

Ok thanks. I will initiate another release later today.

[PBrdng]

@isaacsas v2.10.0 should be available now.

[isaacsas]

Thanks!
