Install the pinned node when the installed one is another major version (closes #118)
script/bootstrap used whatever node was installed, so on the CI runner
image, which ships node 24, the pinned yarn 1.22.22 ran under node 24
and printed the deprecation warning DEP0169 on every bootstrap. It now
uses the installed node only when its major version is the pinned one,
and otherwise installs the pinned node with nvm, as it already did when
node was missing, with yarn and the packages under it. Only the major is
compared because the Dockerfile stages use a node 22 alpine image that
nvm cannot replace. script/fmt and script/fmt-check carry the same test
to pick their yarn: the yarn on PATH, or yarn under the pinned node
loaded through nvm.
