Max buffer count reached for L1MetadataArray_test

[eszpotanski]

L1MetadataArray_test_generate_abstract fails with [ERROR RSZ-0060] Max buffer count reached. error on newer OpenROAD. CI: https://github.com/The-OpenROAD-Project/megaboom/actions/runs/8708125043/job/23884744619#step:7:4378

This error looks like a problem with OpenROAD itself or the configuration for the build error. It appeared after Docker image had been updated - OpenROAD-flow-scripts hash used inside the image: 4ac2d01

Fixed by #43

@eszpotanski I merged #43, but there are some fixes required to .github/ folder to reflect that L1MetadataArray_test only tests up to and including place now. CI is still trying to build L1MetadataArray_test_cts and L1MetadataArray_test_cts_make, which don't exist.

Could you create a PR to fix this?

Thanks!
