docs: remove commit with internal-only changes from `CHANGELOG.md` (#39704)
docs: remove commit with internal-only changes from `CHANGELOG.md` (#39704)

Commit 4ca1c736bb020de166b6a1fbfb9fe264602ccd5c (part of PR #38931) was
incorrectly marked with scope `packaging`, while it is an internal-only
change (i.e. it does not affect packaging). As such is should have been
marked with a different scope (for example, `ci`/`build`/`refactoring`)
and should not appear in `CHANGELOG.md`.

This commit removes the entry from `CHANGELOG.md` to avoid confusing
developers trying to understand how this change may affect their apps.

NOTE:
The commit contains a breaking change notice (about dropping support for
IE<11) which _is_ relevant to app developers. This breaking change
notice is preserved in the "BREAKING CHANGES" section, but the scope is
changes from `packaging` to `core` to avoid confusion.
