Api add support bulk pause resume

[megan-parker]

Endpoint for Bulk Updates to DAGs

Currently the Airflow REST API only allows us to pause/resume (update) one DAG per request. We often need to pause/resume DAGs in bulk. To avoid maintaining a separate set of custom endpoints that will be fragile, it makes sense to update the patch_dag endpoint to handle bulk requests.

Read the Pull Request Guidelines for more information.
In case of fundamental code change, Airflow Improvement Proposal (AIP) is needed.
In case of a new dependency, check compliance with the ASF 3rd Party License Policy.
In case of backwards incompatible changes please leave a note in UPDATING.md.

Congratulations on your first Pull Request and welcome to the Apache Airflow community! If you have any issues or are unsure about any anything please check our Contribution Guide (https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst)
Here are some useful points:

• Pay attention to the quality of your code (flake8, mypy and type annotations). Our pre-commits will help you with that.
• In case of a new feature add useful documentation (in docstrings or in docs/ directory). Adding a new operator? Check this short guide Consider adding an example DAG that shows how users should use it.
• Consider using Breeze environment for testing locally, it’s a heavy docker but it ships with a working Airflow and a lot of integrations.
• Be patient and persistent. It might take some time to get a review or get the final approval from Committers.
• Please follow ASF Code of Conduct for all communication including (but not limited to) comments on Pull Requests, Mailing list and Slack.
• Be sure to read the Airflow Coding style.
  Apache Airflow is a community-driven project and together we are making it better 🚀.

@ephraimbuddy could you please review again?

[ephraimbuddy]

Overall, it looks good. Yea, the dag_id_pattern is required on the patch endpoint but not required on get endpoint. I suggest to only work on the patch endpoint in this PR and work on the get endpoint in a separate PR.

[ephraimbuddy]

LGTM.
One more ask, add a test to validate that the dag_id_pattern is required for this endpoint to avoid someone removing it in the future

The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease.

Awesome work, congrats on your first merged pull request!
