A bit of housekeeping: This PR fixes broken and outdated badges and updates CI (eg testing of `min` instead of hardcoded `1.0`; removing hardcoded architectures which are not appropriate for...

Addresses https://github.com/SciML/Static.jl/issues/144. As ExplicitImports (also previous versions) only supports Julia > 1.7, I used the opportunity to update the Julia compat entry to 1.10.

A sketch of how https://github.com/JuliaNLSolvers/NLSolversBase.jl/pull/168 could be used in LineSearches.jl. A possible downside could be that `gradient(df)` would not return the gradient of the objective function at `x_new` anymore, so...

I recently came across a (numerically) quite challenging optimization problem where the gradient and Hessian would sometimes become non-finite (contain `Inf` or `NaN`s) for unfortunate parameter configurations. Unfortunately, it seemed...

Merely to check the major changes in Optim, LineSearches, and NLSolversBase before releasing them.
