release workflow: fix broken npm update

The release workflow wants to use --provenance but the update fails:

Run npm install -g npm
npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/share/man/man7
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/share/man/man7'
npm ERR!  [Error: EACCES: permission denied, mkdir '/usr/local/share/man/man7'] {
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'mkdir',
npm ERR!   path: '/usr/local/share/man/man7'
npm ERR! }
npm ERR!
npm ERR! The operation was rejected by your operating system.
npm ERR! It is likely you do not have the permissions to access this file as the current user
npm ERR!
npm ERR! If you believe this might be a permissions issue, please double-check the
npm ERR! permissions of the file and its containing directories, or try running
npm ERR! the command again as root/Administrator.

So we fix it by just telling the action what we want rather than monkey patching it.
