Add support for new hubspot editor

[kb1995]

I need to add support for the new hubspot editor forms while still supporting legacy forms. I tried to implement it by changing the src prop, but this breaks the legacy forms. And if I add two scripts (one for legacy and one for the new editor), sometimes I get two forms being rendered.

I’m no longer actively using HubSpot in my daily work, so I don’t have plans to implement new features.

However, I’m happy to review and accept any MRs that adds support for the new editor without breaking existing functionality
