docs: Disambiguate a pair of rST labels

According to the reStructuredText documentation, internal hyperlink
targets[1] are intended to resolve within the current document.

Sphinx has a bug that causes internal hyperlinks declared with
duplicate names to resolve nondeterministically, producing incorrect
documentation. Sphinx does not yet emit a warning when these
duplicate target names are declared.

To improve the reproducibility and correctness of the HTML
documentation, disambiguate two labels both previously titled
"submit_improvements".
