Description:

The pystac/static/fields-normalized.json file appears to be part of package date but it seems that it is not installed.
The PR modifies slightly the pyproject.toml file to properly declare pystac/static/fields-normalized.json properly and install it.

I don't think we need to do anything with pyproject.toml, since package data are included by default w/ setuptools. I think what we need is MANIFEST.in entries, ala https://github.com/stac-utils/pystac/pull/1181/files#diff-41d5a52589e0480be9c099d2bba7a8135b8b0d71bcbb8df3582a8df1c2295003R1?
