FYI @aprilnovak

• I tightened the solver's tolerances in bison.i used in tutorials/pincell_multiphysics.openmc and regolded test results. Before that, this test was passing locally but failing on Civet. Upon inspection, I found that MOOSE was converging to slightly two different temperature fields on Civet vs. my machine which would result in different k_eff solutions in the test

• I also added abs_zero=1e-8 to test:transfers/nek_flux.flux where the csvdiff test was failing with:

test:transfers/nek_flux.flux: ERROR: In file nek_out.csv: The values in column "max_error" don't match at row 1 (time = 0.0005). 
test:transfers/nek_flux.flux: 	relative diff:   1.988e-09 ~ 1.988e-09 = 7.863e-05 (7.863e-05)

@aprilnovak @nuclearkevin idaholab/virtual_test_bed#796 should fix the VTB tests failure, but I'm not sure I understand the nekrs tests failures. Could you help with this?

To be honest, I have no idea why NekRS is failing on those tests. It appears to be happening when loading the mesh, which could indicate an MPI issue on the testing hardware (though, as far as I know CIVET doesn't run these tests in parallel).
