docs: fix indentation of NOSCRIPT recovery example

The last six lines of the recovery example started at column 0, so Sphinx ended the code:: python block early and rendered the example as two disconnected chunks.

Also add resharding and idempotent to the spellcheck wordlist; they are the only words in the new prose that aspell does not know.
