feat(contracts): New contract templates

[al3mart]

Adds new templates with PSPs implementations

• PSP22
• PSP34

Also includes new templates with examples for ink! smart contracts implementing:

• Cross contract calls
• DNS
• Multisig

Changes ContractType for ContractProvider.
Sets Provider as PROPERTY in the TEMPLATE implementation for Contract .
Maintains Type as it could be useful in the future.

Directories within the templates are now copied along with their content. frontend folders included in templates are excluded.

Due to the different repository structure between the available templates, introduces a small patch to properly extract the files of the cloned repo.

Could you merge/rebase please? There were some recent improvements to the new contract command experience which are missing. Tried to do it quickly locally but it showed conflicts which dont seem to show up here.
