build: Constrain astroid to fix make upgrade.

The latest version of pylint pins back astroid to an older version. This
hold back is not caught in the docs requirements file and since both the
docs and testing file are required in the development.in file, we fail
to compile development.txt because of conflicting dependencies.

Holding astroid back until pylint releases a new version that works with
the latest version of astroid.

Created #38066 to undo
this.
