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](https://www.google.com/recaptcha/). This requires API keys from Google. If your homeserver is Dendrite then [hCapcha](https://www.hcaptcha.com) 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:
```yaml
# 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
```yaml
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'
```
