Fix incompatible JS major versions

[ntarocco]

pywebpack v2.0.0 enforces to have the same major versions when installing the same JS package from different modules.
Looking at the code, the only one that require fixes is react-invenio-forms:

• invenio_app_rdm/theme/webpack.py: "react-invenio-forms": "^3.0.0
• invenio_communities/webpack.py: "react-invenio-forms": "^2.0.0" - PR
• invenio_search_ui/webpack.py: "react-invenio-forms": "^1.0.0" - PR
• invenio_vocabularies/webpack.py: "react-invenio-forms": "^2.0.0" - PR
• invenio_rdm_records/webpack.py"react-invenio-forms": "^2.0.0" - PR
• invenio_administration/webpack.py: "react-invenio-forms": "^1.0.0" - PR

It is a good opportunity to also fix the same in the various package.json.
