Fix composer validation errors

Problem/Motivation

There are some problems with the composer.json file. When "composer validate" is executed it gives this error:

Root package 'drupal/geolocation' cannot require itself in its composer.json

This comes from the require-dev lines that are unnecessary IMHO.

Steps to reproduce

Run "composer validate" in the codebase.

Proposed resolution

Remove the "require-dev" items, they're unnecessary.
