xtask: Disable pusing during publish (zellij-org#3040)

* xtask: Add `--no-push` flag to `publish`

which can be used when simulating releases to work without a writable
git fork of the zellij code.

* xtask: Fix borrow issues

* xtask/pipe: Require lockfile in publish

to avoid errors from invalid dependency versions.

* CHANGELOG: Add PR zellij-org#3040.
