Add dendrite captcha config to doc and hCaptcha (#2290)
* added dendrite captcha options

* added hcaptcha doc

* proper url

* Apply suggestions from code review

Co-authored-by: Slavi Pantaleev <slavi@devture.com>

* Update main.yml

* renamed captcha vars to new naming scheme

* change vars to new format

* Rename back some incorrect renamed variables

These variables are either not just part of the `client_api` subsection,
or are not even part of that section at all. They shouldn't have been
renamed in baaef2ed616e2645550d9

* Fix up naming inconsistencies

Some of these variables had been renamed in one place,
but not in other places, so it couldn't have worked that way.

* Add validation/deprecation for renamed Dendrite variables

Overview

Captcha can be enabled for this home server. This file explains how to do that. The captcha mechanism used is Google's ReCaptcha. This requires API keys from Google. If your homeserver is Dendrite then hCapcha can be used instead.

ReCaptcha

Getting keys

Requires a site/secret key pair from:

http://www.google.com/recaptcha/admin

Must be a reCAPTCHA v2 key using the "I'm not a robot" Checkbox option

Setting ReCaptcha keys

Once registered as above, set the following values:

# for Synapse
matrix_synapse_enable_registration_captcha: true
matrix_synapse_recaptcha_public_key: 'YOUR_SITE_KEY'
matrix_synapse_recaptcha_private_key: 'YOUR_SECRET_KEY'

# for Dendrite
matrix_dendrite_client_api_enable_registration_captcha: true
matrix_dendrite_client_api_recaptcha_public_key: 'YOUR_SITE_KEY'
matrix_dendrite_client_api_recaptcha_private_key: 'YOUR_SECRET_KEY'

hCaptcha

Getting keys

Requires a site/secret key pair from:

https://dashboard.hcaptcha.com/sites/new

Setting hCaptcha keys

matrix_dendrite_client_api_enable_registration_captcha: true
matrix_dendrite_client_api_recaptcha_public_key: 'YOUR_SITE_KEY'
matrix_dendrite_client_api_recaptcha_private_key: 'YOUR_SECRET_KEY'

matrix_dendrite_client_api_recaptcha_siteverify_api: 'https://hcaptcha.com/siteverify'
matrix_dendrite_client_api_recaptcha_api_js_url: 'https://js.hcaptcha.com/1/api.js'
matrix_dendrite_client_api_recaptcha_form_field: 'h-captcha-response'
matrix_dendrite_client_api_recaptcha_sitekey_class: 'h-captcha'
