Upgrade Yarn to 4.18.0

Two config keys come with this. `enableScripts` flipped its default to
false in the 4.13 line as supply-chain hardening, so it has to be set
explicitly here — esbuild, @swc/core and @parcel/watcher all need their
install scripts, as does the `electron-builder install-app-deps`
postinstall. `yarn set version` also wrote `approvedGitRepositories: **`,
a blanket opt-out of the new git-dependency approval prompt; that is
dropped again, since the lockfile has no git dependencies and leaving the
guard armed costs nothing until one is added.

The lockfile moves to metadata version 10 and one builtin patch hash for
`resolve` changes; no package resolutions move.

Incidentally this makes `--no-time-gate` available on `yarn add`/`yarn up`,
which 4.11 did not have — the npmMinimalAgeGate quarantine previously had
to be worked around with YARN_NPM_MINIMAL_AGE_GATE=0.
