[PR] Add reproducible build check step in the proces of Provider releases [airflow]

potiuk opened a new pull request, #35871:
URL: https://github.com/apache/airflow/pull/35871

   The reproducible build we just added makes it possible to run full reproducible package builds (byte-to-byte reproducible) - which means that whoever uses the same sources of Airflow (and official 3rd-party build tools) should get identical, byte-to-byte reproducible packages.
   
   This PR updates process of Provider package verification to make sure the packages are binary-identical, thus removing the need of verifying the sources included in the package (allowing to verify not only the sources coming from the repository, but also the generated content (such as get_provider_info.py files).
   
   One step closer to SLSA compliance of our build/release process.

   > Really nice
   
   Indeeed. Those "reproducible builds" - once we have good tooling - are really powerful in making "secure" supply chain possible

+### Reproducible package builds checks
+
+For provider packages we introduced a reproducible build mechanism - which means that whoever wants
+to use sources of Airflow from the release tag, can reproducibly build the same "wheel" and "sdist"
+packages as the release manager and they will be byte-by-byte identical, which makes them easy to
+verify - if they came from the same sources. This build is only done using released dependencies
+from PyPI and source code in our repository - no other binary dependencies are used during the build
+process and if the packages produced are byte-by-byte identical with one that we can do from tagged sources

Review Comment:
   ```suggestion
   process and if the packages produced are byte-by-byte identical with the one we create from tagged sources
   ```
