   Follow-up to #32429, built on top of it.

   This PR addresses the #32429 (review) that the RPC documentation does not use OUTPUT_TYPES, but rather hardcodes them, as is already the case for the getnewaddress command. So here the output types are changed from std::string to std::string_view so that the values are known at compile time or during the early stages of program startup, before main() execution.

   It also updates wallet/rpc/addresses.cpp to write the RPC docs according to OUTPUT_TYPES instead of using hardcoded version.

   🚧 At least one of the CI tasks failed. Task ARM, unit tests, no functional tests: https://github.com/bitcoin/bitcoin/runs/41767168365 LLM reason (✨ experimental): The CI failure is due to a “/*” within a comment, which is treated as an error.

   Try to run the tests locally, according to the documentation. However, a CI failure may still happen due to a number of reasons, for example:

   • Possibly due to a silent merge conflict (the changes in this pull request being incompatible with the current code in the target branch). If so, make sure to rebase on the latest commit of the target branch.

   • A sanitizer issue, which can only be found by compiling with the sanitizer and running the affected test.

   • An intermittent issue.

   Leave a comment here, if you need help tracking down a confusing failure.
