Node 22: fs.Stats constructor is deprecated

[RobinTail]

For your information, this warning appears when running vitest in Node 22 environment:

(node:2057) [DEP0180] DeprecationWarning: fs.Stats constructor is deprecated.

I managed to figure out that it comes from mlly being the dependency of vitest:

=> Found "mlly@1.6.1"
info Reasons this module exists
   - "vitest#local-pkg" depends on it
   - Hoisted from "vitest#local-pkg#mlly"
   - Hoisted from "vitest#local-pkg#pkg-types#mlly"

The exact statement causing the issue is not present in the source code of mlly, but is generated in its build/distribution by rollup:

Consider upgrading rollup and its relatives, or adjust the line of code that may lead to that statement in production.

There is also a duplication of rollup in your lock file:

mlly/pnpm-lock.yaml

This was an upstream issue (wooorm/import-meta-resolve#27) which is resolved in v4.1.0 of import-meta-resolve, but because mlly inline import-meta-resolve, it may take a little while for the fix to percolate downward.

Fix already merged via #249
