I noticed this bug when working on hyperdrive.el, which I had installed
with package-vc-install-from-checkout.  I updated the version of its
transient.el dependency in the Package-Requires header and attempted to
reinstall, but it did not attempt to update the dependency.

I think the attached patch may not be the whole solution.  I applied it,
attempted package-vc-install-from-checkout again, and got this error:

package--with-response-buffer-1: https://melpa.org/packages/transient-20241004.1739.tar: Not found

Do we need to call package-refresh-contents at some point inside of
package-vc-install-dependencies?

Thank you!

Joseph
