   The address from BIP21 examples seems invalid.

   I’m failing to parse it using BDK flutter with the error AddressException( Base58 encoding error: base58ck checksum 0x29619c8a does not match expected 0x11619c8a )

   Online tools also fails to validate it.

   This commit replace the address 175tWpb8K1S7NmH4Zx6rewF9WQrcZv245W by 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2 from the Bitcoin wiki to save debugging time for devs that may face the same issue in the future.

   This may have been on purpose, given that it is examples and not test vectors, because in the past people have sent money to addresses published in BIPs or Bitcoin books which were no longer held by anyone or for which it was then unclear where the funds should be sent.
