pull.rebase config option broken in 2.33.1

Hi!

After update from 2.33.0 to 2.33.1 the pull.rebase = true option no longer works: `git pull` no longer tries to rebase (however manual `git pull --rebase` works fine):

% git config pull.rebase
true
% git pull
fatal: Not possible to fast-forward, aborting.
% git pull --rebase
Successfully rebased and updated refs/heads/local-fixes.
% git pull
fatal: Not possible to fast-forward, aborting.
% grep -C1 rebase .git/config
[pull]
	rebase = true
[rebase]
	autostash = true

After downgrade to 2.33.0:

% git pull Current branch local-fixes is up to date.
