fix: issues after MetaMask update with breaking changes

[navFooh]

Fixes the following issues:

• The wallet_enable method has been replaced with wallet_requestSnaps, passing params as an object, not an array. https://docs.metamask.io/guide/snaps-rpc-api.html#wallet-requestsnaps
• Calls to RPC method wallet_snap_* should now be sent with the params as a single object, not as an array. https://docs.metamask.io/guide/snaps-rpc-api.html#wallet-snap
• The endowment:rpc permission should now be granted to the snap in order to receive RPC calls. My assumption is that only the dapps property needs to be true and not the snaps property. https://docs.metamask.io/guide/snaps-permissions.html#endowment-rpc

Something seems to go wrong with linking the packages when running the demo locally, since I get the following error:

Failed to compile.
./src/containers/MetaMaskConnector/MetaMaskConnector.tsx
Module not found: Can't resolve '@chainsafe/filsnap-adapter' in 'C:\dev\chainsafe\filsnap\packages\example\src\containers\MetaMaskConnector'

However, I've been able to test the RPC changes in my local project and that seems to work fine.
The only problem is that I still get the error about the snap permissions and I'm not sure if we can even test that properly without first deploying the new snap version and installing it in MetaMask.

Thanks for taking the time to contribute to a project, we appreciate any community help.

Most of the PR looks good but it covering breaking changes related to the adapter, unfortunate there is more related to the snap itself, @irubido can you please check in detail?
(even merge and do rest work on top of it)

Hi @navFooh
I appreciate the effort of updating filsnap, adapter changes you made are on the right track, there's just a couple of more things are needed with it, and updating snap itself.
I already started working on the updating filsnap adapter and snap, and PR will be ready soon.
Thanks for your effort
