Improve README documentation

- Update badges: Replace outdated Gitter badge with Zulip chat link and add CI status badge
- Fix documentation links: Update JuliaDiffEq URLs to current SciML docs (docs.sciml.ai)
- Remove outdated ParameterizedFunctions.jl requirement (package works with regular functions)
- Add "Available Solvers" section documenting all 8 MATLAB solver bindings
- Fix typos: "timeseries_error" -> "timeseries_errors", "overhead of over" -> "overhead of"
- Add missing comma in option list

 MATLABDiffEq.jl is a common interface binding for the [MATLAB](https://www.mathworks.com/products/matlab.html) ordinary differential equation solvers. It uses the [MATLAB.jl](https://github.com/JuliaInterop/MATLAB.jl) interop in order to

 and helping new users migrate models over to Julia.

 Note that the algorithms are defined to have the same name as the MATLAB algorithms,
 but are not exported. Thus to use `ode45`, you would specify the algorithm as

+To measure the overhead of the wrapper, note that the variables
 from the session will be still stored in MATLAB after the computation
 is done. Thus you can simply call the same ODE function and time it
