CU-86dthh0nm - Update NeoToken native contract

[luc10921]

Summary or solution description
Added get_committee_address and get_register_price to the NeoToken native contract interface at boa3.sc.contracts

How to Reproduce

from boa3.sc.compiletime import public
from boa3.sc.contracts import NeoToken


@public
def main() -> int:
    return NeoToken.get_register_price()

Tests

neo3-boa/boa3_test/tests/compiler_tests/test_native/test_neo.py

Lines 589 to 603 in 570584a

	async def test_get_committee_address(self):
	expected_output = (
	Opcode.CALLT + b'\x00\x00'
	+ Opcode.RET
	)
	output, _ = self.assertCompile('GetCommitteeAddress.py')
	self.assertEqual(expected_output, output)
	async def test_get_register_price(self):
	await self.set_up_contract('GetRegisterPrice.py')
	register_price = await self.get_register_price()
	result, _ = await self.call('main', [], return_type=int)
	self.assertEqual(register_price, result)

Platform:

• OS: Windows 11 x64
• Python version: Python 3.11

(Optional) Additional context
Couldn't test the get_committee_address method with the current neo-go config, so it's just checking the opcode and it was invoked on the testnet.
