Fix unused footnote and add warnonly for :footnote in makedocs

Fix the unused [^2] footnote in EGFR_Benchmark.md that was breaking the
Documenter build. Also add warnonly=[:footnote] to makedocs so that future
footnote issues in auto-generated benchmark markdown don't break the entire
documentation build.

+We will benchmark the aggregators of JumpProcesses on a epidermal growth factor receptor signaling network (356 species, 3749 reactions)[^1], modeled using Catalyst.jl[^2].
 
 Let's first look at how the model equilibriates to make sure we get consistent results for all the methods. Let's plot the dimer concentration as a function of time using each of the different stochastic simulation algorithms.
