geographical terms/"is it modified?" parent issue

Regarding the requirement for geo_loc_name "geographic location (country and/or sea,region)" and lat_lon "geographic location (latitude and longitude)" and the resulting DH section assignment:

For the SNTC/DataHarmonizer workflow, I was taking MIxS' soil class as the source of truth. Now, in nmdc-dh-sheets/sheets_and_friends, I'm using the MIxS checklist/environmental combination soil MIMS as the source of truth, so the usage of environmental terms is clearer. That explains why I waffled on whether these fields were required in our soil_emsl_jgi_mg interface for GSP.

Having said that, we are modifying the validation pattern for lat_lon from the string serialization of {float} {float} to the regular expression ^[-+]?([1-8]?\d(\.\d+)?|90(\.0+)?)\s[-+]?(180(\.0+)?|((1[0-7]\d)|([1-9]?\d))(\.\d+)?)$ so we won't get locations like "1000.1 555.5". So it is modified in that sense.

You can see all of MIxS' metadata on these two terms in three different contexts below. Again, I am using soil MIMS (aka soil microbiome) as the reference now.
