<https://github.com/RTimothyEdwards/open_pdks/issues/269|#269 sky130 antenna cell has the wrong type>
New issue created by <https://github.com/maliberty|maliberty>
The discussion in <https://github.com/The-OpenROAD-Project/OpenROAD/pull/2136|The-OpenROAD-Project/OpenROAD#2136> highlights that

```
MACRO sky130_fd_sc_hd__diode_2
  CLASS CORE ;
```

is incorrect and should be

```
MACRO sky130_fd_sc_hd__diode_2
  CLASS CORE ANTENNACELL ;
```

Since I can't get anything fixed in upstream Google repos I am hoping you can fix it here. This happens in sky130 A &amp; B.
