Rather than hardcode two builders, allow builders to specify a `builder-detect` trigger. This trigger can be used to specify if the builder should or should not be used for an application. Each builder takes stdin and can decide if it wants to emit it or emit it's own image source type.
If the final value is empty, then Dokku will default to herokuish (and cnb once that is stable). In addition, a future change may allow users to manually specify a builder in the case they wish to override the choice selected by Dokku.
This change enables users to build custom builder plugins and have those plugins used for building an image asset. By way of example, an enterprising user could create a `builder-lambda` based on lambci, and then pair this with a scheduler plugin that updates a lambda function on AWS. Alternatively, a user might decide they wish to place their Dockerfile in a specific directory for their applications - such as an `_infrastructure` directory - and create a plugin to override how that is detected within Dokku.
This occurs during the postdeploy on the first deploy of an app, mimicking heroku. It currently happens _after_ the `postdeploy` and `release` deploy tasks.

## 0.23.9
Install/update via the bootstrap script:
```shell
wget https://raw.githubusercontent.com/dokku/dokku/v0.23.9/bootstrap.sh
sudo DOKKU_TAG=v0.23.9 bash bootstrap.sh
```
### Refactors
- #4445: @josegonzalez Bump azure template and formula directly on release
### Documentation
- #4444: @josegonzalez Uuse updated links for documentation
- #4439: @RyukerLiu View Doc redirect not working. Change to use direct link
Rather than try and do something fancy on tag creation via workflows - which won't trigger due to workflows not being able to trigger other workflows without using workflow_run on the downstream workflow as a trigger - we just do all the releasing at once. This makes it easy to understand whether a release fully completed.
