content: donor guide privacy section — Bisq as an example, nonlogs.io link, softer exchange warning

- 'Acquire Grin without KYC' copy now names Bisq as one option, not the
  only one.
- 'Skip the public receipt' now links to nonlogs.io (no-KYC exchange)
  instead of a coinjoin wallet, which didn't match the card's point.
- 'Exchanges know who you are' overstated that all exchanges track
  withdrawals; softened to 'some' and points to nonlogs.io as the
  no-KYC alternative.
