It was supposed to update a local branch in case the remote branch was
updated between actions/checkout and the end of tool/sync_default_gems.rb.
Note that this `git pull` didn't exist in the original bin/update-default-gem.sh
d9e9bcc60d,
so it was newly introduced at 3ba5cfd1cb.
But `git pull --no-ff` failed when master had updates in an unrelated
repository. I think we need to use `git pull --rebase` instead.
This fixes:

At the moment, we're not sure which gem relies on past renames. So we
try this, and revert it if it turns out to be necessary.
Given that it slows down every single sync, however, I'm thinking of
making tool/sync_default_gems.rb responsible for implementing all
necessary renames on cherry-picks using filter-branch (or any
modification on commits before pushing them).
