This removes sha1 hashes from yarn.lock. Compliant with microsoft hashing. This adds the yarn berry config / package files: .yarn/ project-local workspace and .yarnrc.yml berry config Here we bootstrap yarnin devcontainer postCreate

@sam-byng I approved, but can you create an issue against the features repo, so that we can allow for newer versions of yarn please? |

NOTE: SHA-1 is not allowed for any purpose, visit Microsoft.Security.Cryptography.10021 for details.
Therefore bumped to latest yarn javascript package manager to avoid sha1 hashing of package binaries.
This adds the yarn berry config / package files: .yarn/ project-local workspace and .yarnrc.yml berry config
Note: Here we bootstrap yarn in devcontainer postCreate. WE also download yarn 4.9.4 locally and refer to it from package.json. Just in case devcontainers not used.
