Set tfa_rules's "Ecosystem" on the project page

Problem/Motivation

As a site builder browsing for modules on Drupal.org, I want to find a list of modules which extend the Two-factor Authentication module, so that I can find a way to implement TFA on my site.

As a site builder browsing for modules on Drupal.org, I want to find a list of modules which extend the Rules module, so that I can find Rules triggers, conditions, and actions which meet my needs.

Proposed resolution

Drupal.org recently added an "Ecosystem" field (field_project_ecosystem) to project pages in #1323826: Make it easier to identify and discover ecosystem modules. This module (tfa_rules) is part of two ecosystems: the Two-factor Authentication module ecosystem, and the Rules module ecosystem. Adding a reference to both modules would make it easier for others to find this module.

Remaining tasks

(only a project maintainer or a Drupal.org admin can complete these steps)

1. Go to https://www.drupal.org/node/2541496/edit (i.e.: the edit form for this module's project page)
2. At the bottom of the "Project classification" field-set, there is an "Ecosystem" field. In the (first) textbox, type "Two-factor Authentication (TFA)" and choose it from the drop-down. It will expand to "Two-factor Authentication (TFA) (1099690)". Click "Add another item". A second textbox appears. In the second textbox, type "Rules" and choose it from the drop-down. It will expand to "Rules (190124)".
3. Scroll down to the bottom and click "Save"

Once this is completed, there will be:

1. a link on the tfa_rules project page, in the "Project information" section, which says "Ecosystem: Two-factor Authentication (TFA)", and
2. on the the Two-factor Authentication module's project page, in the sidebar under "Resources" there will be a "Projects that extend this" link — clicking on this will display a list of "Ecosystem modules for Two-factor Authentication (TFA)" that will include tfa_rules
3. on the Rules module ecosystem page
