remove -i option from sed (#1389)

# Description

@swift-nav/devinfra

cargo release uses a pre-commit hook to update the sbp2json input to
point to the latest sbp release in crates.io

However, the sed version uses the `-i` flag which is not POSIX defined
and will give different results with gnu sed vs BSD sed.

Now this should be good to release from OSX or linux
