Clean up Vault docs in User Guide. (#46188)

* Fix spelling of 'separate' throughout.

* Various cleanups in the User Guide for Vault.

- Fix spelling of 'algorithm'
- Fix indentation of nested list in payload format
- Fix mysterious refernce to 'b_pkey1'.
- Fix reference to newline as '\n': the backslash is lost when rendered
to the docs website. Specify the hex value for newline instead of the
backslash escape.

* Fix formatting

* Update vault.rst
