[Meta] Fix route social_auth_*.settings_form does not exist

Problem/Motivation

Several 4.x implementations specify social_auth_*.settings_form in their hook_help and *.info.yml implementations, causing a Route "social_auth_github.settings_form" does not exist." error on install.

Steps to reproduce

Composer require and install via Drush any of the following:

• social_auth_amazon
• social_auth_microsoft
• social_auth_github

You may see the implmentations at the links below:

• social_auth_microsoft.module
• social_auth_microsoft.info.yml
• social_auth_github.module
• social_auth_github.info.yml
• social_auth_amazon.module
• social_auth_amazon.info.yml

Proposed resolution

Correct the help route to help.page.social_auth_* (e.g. help.page.social_auth_discord).

As per the docs, correct the *.info.yml:

configure: social_auth.network.settings_form
configure_parameters:
  network: discord

Remaining tasks

Create the tickets for each module, and link this issue as the parent.
