docs: sync 2.2 changelog and news to main (#3901)

The 2.2 release was completed, but the changelog updates and news file
deletions were only performed on the release branch. We need to sync
these changes back to main so that they are reflected in the unreleased
state and future releases.

 * Fixed a flaky error on Windows 2022 when looking up the win32 version during
 site initialization by retrying the lookup
 ([#3721](https://github.com/bazel-contrib/rules_python/issues/3721)).
+* (binaries) Fixed building of legacy zipapps on Windows execution platforms by
+  using a hermetic tool instead of host `cat`.
+* (bootstrap) Fixed stage 1 bootstrap imports when target outputs shadow
+  standard library modules.
 * (coverage) Skip lcov report when no data was collected.
 * (pypi) Fixed `experimental_index_url` checking truthiness before envsubst
 expansion.
 * (rules) Fixed venv output paths for `py_binary` and `py_test` targets whose
 names contain path separators so distinct targets with the same basename no
 longer share the same venv output directory.
+* (windows) Fixed build data generation on localized Windows installations.

 * Exposed {bzl:obj}`VenvSymlinkEntry` and {bzl:obj}`VenvSymlinkKind` in

 * (pypi) Added `@pypi` repo: a unified hub of `pip.parse` hubs.
+* (pypi) Added a `dep` tag class to the `pip` bzlmod extension. This allows
+  modules to declare abstract PyPI dependencies, ensuring target structures
+  exist in the unified hub, while allowing other modules to provide the
+  concrete implementation via `pip.parse`.
 * (uv) Support for basic `uv.lock` generation via the `lock` rule
 and basic support for importing the `uv.lock` file itself. Since this
 may have bugs, please report this by creating new tickets.
