Fix tests on Julia nightly

[ararslan]

The tests for specific exception types in sem are relying on the exceptions thrown from deeper in the call stack, outside of this package's control. We do still expect these cases to throw, but since we can't actually control the type of the exception, we can instead test that any exception is thrown.

The test of the number of allocations from calling mad on a generator fails because there are nearly 10x more allocations than the upper bound used in the test. We can mark this test broken with Julia v1.10, and the test will fail if the allocations for this case are improved, be it upstream or in the implementation of mad (if applicable).

Error: 1 docstring not included in the manual:

    StatsBase.addcounts! :: Tuple{AbstractArray, AbstractArray{<:Integer}, UnitRange{<:Integer}}

These are docstrings in the checked modules (configured with the modules keyword)
that are not included in @docs or @autodocs blocks.

ERROR: LoadError: `makedocs` encountered an error (:missing_docs). Terminating build before rendering.

This is so weird. I can reproduce it locally only if there is an existing docs/build directory.

It seems the Documenter issue was fixed upstream (but is not available in 1.9 yet), so this shouldn't hold back the PR, should it?

It sounds like the upstream change that fixed the issue with Documenter will not go into 1.9 (JuliaLang/julia#49975 (comment)).

this shouldn't hold back the PR, should it?

Yeah I suppose not. I had forgotten about this PR but I believe at the time I figured I'd tackle CI issues together but the Documenter thing turned out to really be A Thing.
