The `else` branch (`HEADLESS != 1`) also has an incremented `REPORT_EXPECT_PASS` value: from `93`  to `94`.

Note that the merge with `upstream/master` still leads to the same error:

/bin/grep -s "Test results: passed: ${EXPECT_PASS}; failed: ${EXPECT_FAIL}; error: 88" /home/runner/work/jtreg/jtreg/build/test/ReportOnlyTest.jt.log  > /dev/null
Expect: Test results: passed: 91; failed: 40; error: 88
make: *** [../test/basic/ReportOnlyTest.gmk:45: /home/runner/work/jtreg/jtreg/build/test/ReportOnlyTest.ok] Error 1
