[AIRFLOW-XXX] Improve format in code-block directives

[mik-laj]

Make sure you have checked all steps below.

Jira

• My PR addresses the following Airflow Jira issues and references them in the PR title. For example, "[AIRFLOW-XXX] My Airflow PR"
  • https://issues.apache.org/jira/browse/AIRFLOW-XXX
  • In case you are fixing a typo in the documentation you can prepend your commit with [AIRFLOW-XXX], code changes always need a Jira issue.
  • In case you are proposing a fundamental code change, you need to create an Airflow Improvement Proposal (AIP).
  • In case you are adding a dependency, check if the license complies with the ASF 3rd Party License Policy.

Description

• Here are some details about my PR, including screenshots of any UI changes:

Tests

• My PR adds the following unit tests OR does not need testing for this extremely good reason:

Commits

• My commits all reference Jira issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "How to write a good git commit message":
  1. Subject is separated from body by a blank line
  2. Subject is limited to 50 characters (not including Jira issue reference)
  3. Subject does not end with a period
  4. Subject uses the imperative mood ("add", not "adding")
  5. Body wraps at 72 characters
  6. Body explains "what" and "why", not "how"

Documentation

• In case of new functionality, my PR adds documentation that describes how to use it.
  • All the public functions and the classes in the PR contain docstrings that explain what it does
  • If you implement backwards incompatible changes, please leave a note in the Updating.md so we can assign it to a appropriate release

Minor suggestion - but looks fine to me :)

Suggested change

	.. code-block:: ini
	.. code-block:: cfg

works, too - according to http://pygments.org/docs/lexers/#pygments.lexers.configs.IniLexer

[mik-laj]

In other place, we use ini. I prefer not to introduce many ways to mark the same. https://raw.githubusercontent.com/apache/airflow/dd9071bf5e127d449eee304736d2a5125813f607/docs/usage-cli.rst
This is only information about the file format and pygments select this format by calling this class "Ini*". The information that cfg is also supported is not obvious.
WDYT?
