docs: updating packages version in the README

[synopss]

Current Behavior

With the current version written, there is an error when trying to create an app with nx g @nx-plus/vue:app :

Cannot find module 'nx/src/config/configuration'
Require stack:
- some-project\node_modules\@nx-plus\vue\node_modules\@nrwl\devkit\index.js
- some-project\node_modules\@nx-plus\vue\src\generators\application\generator.js
- some-project\node_modules\nx\src\config\workspaces.js
- some-project\node_modules\nx\src\command-line\generate.js
- some-project\node_modules\nx\src\command-line\nx-commands.js
- some-project\node_modules\nx\bin\init-local.js
- some-project\node_modules\nx\bin\nx.js
- C:\Users\User\AppData\Roaming\nvm\v14.19.1\node_modules\nx\bin\nx.js

Fixes

After using the the same commands with the last version of Nx used by the package, everything is working fine.
