Revert a6287a9 once actions/setup-node@v4 updates to use Node>= 22.5.1

[james-pre]

https://github.com/zen-fs/core/commit/a6287a9bed0aea12b6259084d99efeccd9577459 was made because of https://github.com/npm/cli/issues/7672. GitHub Actions is currently using 22.5.0 when node-version is 22 in the CI workflow, which leads to an error. Once GitHub Actions updates so a node-version of 22 resolves to >= 22.5.1, https://github.com/zen-fs/core/commit/a6287a9bed0aea12b6259084d99efeccd9577459 can be reverted.
