patch 9.1.0134: CI: Test_term_gettitle() is flaky on MacOS 14
Commit: https://github.com/vim/vim/commit/6a46c19b2507bce632b5e67ef31e47e60a95ed10

patch 9.1.0134: CI: Test_term_gettitle() is flaky on MacOS 14
Problem: Test_term_gettitle() is flaky on MacOS 14 and Github runners
Solution: Skip the test on Github CI
closes: #14085
It fails with this: '^\\[No Name\\] - VIM\\d*$' does not match 'e] - VIM'
It is not clear why term_gettitle() only get's the last part of the
expected title (perhaps there is a Carriage return in there or the
terminal window is too small?)
So let's just skip this test for now.
