Fixed
- pnpm lockfiles are read on Psych older than 5.2.5: The version check and doctor read
pnpm-lock.yamlwith
YAML.safe_load_stream, which Psych added in 5.2.5 (Ruby 3.4 ships 5.2.2). On older Psych every pnpm lockfile
read failed silently, so the version check fell back topackage.jsonand doctor'sreact-server-dom-webpack
check reported "could not check". Older Psych now parses the stream and safe-loads each document. Fixes
#5300.
