ci: enable yarn hardened mode only once for the workflow (#2133)

## Proposed change

Since Yarn 4, hardened mode is enable by default on GitHub public pull
requests.
This can considerably slow down the yarn install
See https://yarnpkg.com/features/security#hardened-mode

As recommended, we just need to run it once
