Update AGE macro test

[janebitovi]

I cannot find the specific test this is talking about and since it would have failed again this year if it wasn't fixed, it was likely fixed...
in any case, this line from another AGE test (maybe the one this was talking about?) has this line here to avoid the problem:

const expectedAgeResult = differenceInYears(Date.now(), parseISO('2000-01-01'))

though the git history shows it was a new file when that line was added so no idea if it got moved+fixed at the same time or if it's unrelated....

in any case, it's very likely not happening any more since it didn't happen this year, so I'm closing the issue

This test was fixed, but I must have forgotten to close the issue
