gui: change example address from legacy (P2PKH) to bech32m (P2TR)

Browse Source 
The dummy addresses have been computed with the following Python script
(executed under ./test/functional):

--------------------------------------------------------------------------------------------------------
from test_framework.segwit_addr import CHARSET, decode_segwit_address, encode_segwit_address
from test_framework.messages import sha256

output_key = sha256(b'bitcoin dummy taproot output key')
for network, hrp in [('mainnet', 'bc'), ('signet', 'tb'), ('testnet', 'tb'), ('regtest', 'bcrt')]:
    dummy_address = encode_segwit_address(hrp, 1, output_key)
    while decode_segwit_address(hrp, dummy_address) != (None, None):
        last_char = CHARSET[(CHARSET.index(dummy_address[-1]) + 1) % 32]
        dummy_address = dummy_address[:-1] + last_char
    print(f'{network:7} example address: {dummy_address}')
