Update to webpack-dev-middleware 7.0.0

[reaktivo]

Bug report

Currently webpack-dev-server throws errors when used with Node >20 due to a old memfs being referenced as a transitive dependency.

webpack-dev-middleware has already been updated as of this PR.

Now the last remaining piece is for webpack-dev-server to point to latest webpack-dev-middleware.

Actual Behavior

Throws the following error:

node:events:492
      throw er; // Unhandled 'error' event
      ^

TypeError: Cannot set property closed of #<Readable> which has only a getter
    at FsReadStream.close (/Users/x/dev/client/node_modules/memfs/lib/volume.js:2047:17)
    at FsReadStream._destroy (/Users/x/dev/client/node_modules/memfs/lib/volume.js:2032:10)
    at _destroy (node:internal/streams/destroy:109:10)

Expected Behavior

Should not throw memfs errors
