Add SBOMS generated as artifacts in "canary" build

[potiuk]

Currently, we have "sbom" generation done as part of the release. But it does not happen when "canary" build is executed in main. And @raboof - the Security Response engineer from the ASF is now building automation and exposure of the SBOMs for all ASF projects, so they are interested in being able to retrieve SBOMS from our main build automatically.

We should restore #41931 "Publish docs" scheme and add "update-sbom" command to include SBOM generation from main - so that it can be published in our test site. It should be as easy as running single command during doc publishing and likely fixing it so that it works with main constraints rather than only with released versions.

This is basically the command run to generted SBOM (and here support for main should be added if it does not work:

breeze sbom update-sbom-information --airflow-version ${VERSION} --airflow-site-directory ${AIRFLOW_SITE_DIRECTORY} --force --all-combinations --run-in-parallel

The actual step in release process for that is https://github.com/apache/airflow/blob/main/dev/README_RELEASE_AIRFLOW.md#publish-documentation
