GH_CUTS HDU information in DL3 index table

[SeiyaNozaki]

From #1227

DL3 index table contains the information of IRF HDU.
https://github.com/cta-observatory/cta-lstchain/blob/main/lstchain/high_level/hdu_table.py#L200-L220

It does not contain the GH_CUTS HDU information since this HDU is not created by pyirf function. We define the similar function inside the lstchain. Do we need to add the GH_CUTS HDU information in this index table?

I don't think we use the information from GH_CUTS (or even AL_CUTS) HDU for any high-level analyses. It is mainly used to check the distributions of the cuts applied to get the DL3 file.
Hence it makes less sense to me, to add this information to the HDU index tables (for the sake of completeness).
