Updating land_coords used in local_latlng() to cover every supported country code

Faker version: 23.3.0
OS: macOS Ventura 13.6.4

When using faker.local_latlng method I thought that it has exported locations from geonames.org for every possible country code (which can be generated by faker itself), but it turned out that we have a list of possible locations in faker/faker/providers/geo/__init__.py::Provider:land_coords

Hard-coded values are not the problem though, but the lack of locations for some countries (like mentioned below Grenada (GD)).

Is it possible to update land_coords with additional locations?

Steps to reproduce

x= faker.local_latlng(country_code="GD")

Expected behavior

Something similar to: X is ('12.722', '-61.3729', 'Grenville', 'GD', 'Grenada')

Actual behavior

X is None
