Provide better external url for sourcemap content (#13761)

<!-- Use this checklist to make sure your PR is ready for merge. You may
delete any sections you don't need. -->

## DESCRIBE YOUR PR
These docs were pointing to an outdated url about general sourcemap
info, as pointed out by this user on x
https://x.com/birch_js/status/1910587985558651172.

Just a quick swap to something more meaningful even though some of this
legacy content may not even be surfaced in the latest docs 🧹💨

## LEGAL BOILERPLATE

<!-- Sentry employees and contractors can delete or ignore this section.
-->

Look, I get it. The entity doing business as "Sentry" was incorporated
in the State of Delaware in 2015 as Functional Software, Inc. and is
gonna need some rights from me in order to utilize my contributions in
this here PR. So here's the deal: I retain all rights, title and
interest in and to my contributions, and by keeping this boilerplate
intact I confirm that Sentry can use, modify, copy, and redistribute my
contributions, under Sentry's choice of terms.
