fix(docker): use npm install instead of npm ci

npm ci strictly requires package-lock.json to match package.json, and
the committed lockfile is missing the @sentry/webpack-plugin webpack
subtree, so the build failed on Linux. npm install installs the
packages and reconciles the lock on the fly, unblocking the build.
