Fix Julia master

[devmotion]

In JuliaLang/julia#44360, BLAS.libblas and LAPACK.liblapack were removed. Thus BandedMatrices does not work with Julia nightlies currently, which causes test errors e.g. in PDMats (see e.g. https://github.com/JuliaStats/PDMats.jl/runs/6696362323?check_suite_focus=true).

JuliaLang/julia#44379 added Base.libblas_name and Base.liblapack_name which can be used instead (see FluxML/NNlib.jl#396 and FluxML/NNlib.jl#396 (comment)).

Please don't test on nightly, it's too unreliable

[devmotion]

Sure, I'll revert the commit. I thought it would be good to show at least once though in this PR that the PR actually fixes the issues with Julia nightly that show up in downstream packages.

I reverted the last commit (the test errors on nightly are different from the downstream issues that the PR is supposed to fix).

Bump 🙂

Thanks for merging and releasing this PR! As intended it fixed the downstream CI issues in PDMats: https://github.com/JuliaStats/PDMats.jl/actions/runs/2455339091
