Add instructions for captcha config to README

- This plugin creates an endpoint `/apps/ecloud-accounts/api/set_account_data` that is to be used to set user's email, quota,recovery email and create the user's folder if necessary

### Captcha Configuration for user account creation

- Simple image based captcha is the default for human verification

- To change the value, set `ecloud-accounts.captcha_provider` 

  - Allowed values are `image` (default) and `hcaptcha` (https://hcaptcha.com)

#### HCaptcha Configuration

- For hcaptcha provider to work, set the following values correctly:

  - `ecloud-accounts.hcaptcha_site_key`

  - `ecloud-accounts.hcaptcha_secret`

## Drop account

- The drop account functionality plugin works in conjunction with the drop_account plugin : https://apps.nextcloud.com/apps/drop_account
