update dep for stcal to released version

[braingram]

stcal 1.8.0 was released. We can now go back to using the released version (instead of installing from main). This PR updates the required version to >=1.8.0, <1.9.0. This range will allow installing the "dev" version which will appear as stcal-1.8.1.dev... when a new commit is added to stcal.

The regression tests show 9 failures. All related to miri and likely explained by the CRDS update which mentions:

The pipeline developers plan to remove the parameters nhigh and nlow from the outlier detection code, but they first need to be removed from the parameter reference files. This delivery of MIRI outlier detection parameter reference files removes the parameters nhigh and nlow from the reference files. The values of scale are also being updated to 1.0 0.8 from the previous values of 0.5 0.4, as this gave better results when tested on MIRI calibration data. This change will affect MIRI imager, coronagraphic and LRS slit data.
