Add TEME tests that are not remote_data #10255
Description
#10149 added the TEME frame, and included necessary unit tests. However, the tests are remote_data because that makes sense for the obvious uses cases for this frame (satellites). It's not a huge priority, but it would be a bit more robust (and make our coverage stats look better) if there were some tests for this frame that didn't require remote data.

This is quite a widespread problem, no? Many tests in the coordinates package are marked as remote_data, due to the need to query non-astropy-data for the UTC-UT1 conversion.
Provided this conversion was well tested elsewhere we could remove remote_data marks for many of these tests by manually setting

FWIW -- Yes, you can mock it to avoid internet connection.

That said, it is no fun to mock, and I think it is part of a bigger problem of coordinates importing time causing IERS leap seconds table download. I can't seem to find that issue but I am pretty sure @mhvk knows which one. 😅
