Update bubble plugins list

Hello guys,
After reviewing the wallets documentation we identified 2 wallets that we won't be able to integrate: Parity signer - which we found out they do only native wallets , and Polkadot-js which already exists. Let us know if you have any questions regarding this.

Hello @semuelle . I am getting stuck in the CLA verification. I sign with my verification, but it seems it does not want to accept liisa's. Liisa used to be an account but was converted into an organization. I added the email to my account but still no success. Do you have any idea on how to fix this?

Thanks for the amendment. Don't worry about the GitHub action, it's just for safety but not actually necessary.
