Create Invalidations.yml

[ranocha]

is is based on https://github.com/julia-actions/julia-invalidations. Adding such checks came up in https://discourse.julialang.org/t/potential-performance-regressions-in-julia-1-8-for-special-un-precompiled-type-dispatches-and-how-to-fix-them/86359. I suggest to add this check here since this package is widely used as a dependency.

Thanks for the contributions to JuliaWeb!

For MIMEs.jl, I think that the subject of invalidations does not really apply, because the package contains a small number of simple functions that will never be extended with additional methods. We have 0 invalidations currently ( https://github.com/JuliaWeb/MIMEs.jl/runs/8137852412?check_suite_focus=true#step:9:1 ).

I will close this for now but feel free to continue the discussion and I will re-open. Thanks again!

Hi! First of all, thanks for many great packages. It's great to hear that this package does not cause any invalidations at the moment. We also had some discussion in SciML about this but decided that it's always better for us to accept increased CI workload to reduce human working time, see SciML/MuladdMacro.jl#26 (comment)
You are of course free to make your own decision. My intention was just to provide a tool to help reducing invalidations and thereby latency problems in Julia. If this package is already basically in its final state and will never add invalidations, you don't need to add this, of course.

@ranocha FYI the compat file did not work on Julia 1.11, I had to change it to Julia 1.10 to fix it
