Merge bitcoin/bitcoin#26558: doc: add tr() descriptor example to deriveaddresses

92a4ed05d1 doc: add tr() descriptor example to deriveaddresses (FractalEncrypt)

Pull request description:

  This simple PR adds a missing tr() descriptor example to the `help deriveaddresses` examples.

  - The functionality added in https://github.com/bitcoin/bitcoin/pull/24043 is a significant departure from legacy multisig address creation, yet there is no corresponding tr() descriptor example in the help.
  - Having this example in combination with the examples in the descriptors documentation will be helpful to users.

  I needed this information to correctly create a tr multisig address but was unable. I had to leave the software and use a 3rd party site to ask two separate questions ([1](https://bitcoin.stackexchange.com/questions/115700/how-do-i-create-a-taproot-multisig-address-requiring-21-of-210-keys-to-spend), [2](https://bitcoin.stackexchange.com/questions/115742/signing-psbts-to-spend-from-taproot-multisig-address)) to create an address using the new functionality.

  Note: This specific example is not provided in the [descriptors.md ](https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md) documentation, though there is a similar example with `sortedmulti_a. `
