Move top guzzle7-adapter

It what you report is totally out of the real Geocoder 8.x-4.x actual branch, that as instead the following composer.json requirements:

    "require": {
        "php": ">=7.3.0",
        "php-http/guzzle7-adapter": "^1.0",
        "php-http/message": "^1.6",
        "willdurand/geocoder": "^4.0",
        "davedevelopment/stiphle": "^0.9.2"
    },

as reflection of its actual code base:
https://git.drupalcode.org/project/geocoder/-/blob/8.x-4.x/composer.json...

Closing this, as totally misaligned (untrue),
and also not properly taking into account this parent (duplicate) issue:
