json: Fix package-version-server referencing the wrong path to the binary (#13555)

We were trying to access the binary at
package-version-server-{VERSION}/package-version-server, whereas the
binary itself is placed at package-version-server-{VERSION}

Release Notes:

- Fixed package.json language server failing to start.
