feat: handling of get-starknet v5

[PhilippeR26]

Motivation and Resolution

Add handling of Starknet Wallets with get-starknet V5 library.

Usage related changes

Class WalletAccountV5 has been added.
Namespace walletV5 has been also added.
Detailed usage in the guide.

Development related changes

• In package.json, add of "@wallet-standard/features" to get the type for events (not re-exported by get-starknet).
• Add of "@starknet-io/get-starknet/wallet-standard/features". As get-starknet V5 is not yet released, exact import names are uncertain. That's why this PR is initially tagged as draft. To be finalized once get-starknet released.
• Except events handling (only one event in get-starknet v5), few changes from V4.
• As with WalletAccount V4, it's not possible to test V5 in test suite. Extensive tests will be performed once V5 released, prior to remove the draft tag of this PR.

Checklist:

• Performed a self-review of the code
• Rebased to the last commit of the target branch (or merged it into my branch)
• Documented the changes in code (API docs will be generated automatically)
• All tests are passing

get-starknet is no more beta, and is now v5.0.0.
We can now import type StandardEventsChangeProperties directly from get-starknet, without using @wallet-standard/features lib.
This last commit has been tested with success in the DAPP demo: https://cairo1-js.vercel.app/

This get-starknet v5 PR has been re-based to beta.
@tabaktoni @penovicp : this PR has been tested with starknet v0.14.1 & rpc 0.10.0 in the demo DAPP. It's OK to merge in v9 beta
