Some of these are probably outdated, given that our Julia compat is now at 1.10. But more saliently: the filters are probably not doing what we might like them to do (at least with the current version of Documenter). See https://documenter.juliadocs.org/stable/man/doctests/#Filtering-Doctests

To use a single example,

# Older versions will show "Array{...,1}" instead of "Vector{...}".
r"(Array{.+,\s?1}|Vector{.+})",

What we probably want here is to replace Array{...,1} with Vector{...} when performing the doctests, so as per the Documenter docs, I think the filter should be

r"(Array{(.+),\s?1}" => s"Vector{\1})",

Instead, what the current filter does is to simply remove any lines which match the regex. This means any line of output in the doctests that contains either Array{...,1} or Vector{...} is simply ignored, which leads to false test successes.

Although note that the regex+substitution pair can't be specified as part of the call to doctest(). They have to be specified for each test individually. JuliaDocs/Documenter.jl#2360
