Only build one awx image instead of separate web and task images

 This is a list of high-level changes for each release of AWX. A full list of commits can be found at `https://github.com/ansible/awx/releases/tag/<version>`.
 
 ## 12.0.0 (TBD)
+- Moved to a single container image build instead of separate awx_web and awx_task images. The container image is just `awx` (https://github.com/ansible/awx/pull/7228)
 - Official AWX container image builds now use a two-stage container build process that notably reduces the size of our published images (https://github.com/ansible/awx/pull/7017)
 - Removed support for HipChat notifications ([EoL announcement](https://www.atlassian.com/partnerships/slack/faq#faq-98b17ca3-247f-423b-9a78-70a91681eff0)); all previously-created HipChat notification templates will be deleted due to this removal.
 - Fixed a bug which broke AWX installations with oc version 4.3 (https://github.com/ansible/awx/pull/6948/files)
