crypto: importer: Update with fetch

Instead of doing a "pull --rebase" to update to the latest development
branch, do a "fetch" followed by a "checkout" to update to the specified
release. This enables us to get any new tags created since the last
update to the development branch, and removes the noise of updating a
local "development" branch.
