* [Windows] Fix MongoDB installer after release-notes URL and anchor change

The release-notes URL with a trailing slash now answers 308 Permanent
Redirect, which Invoke-WebRequest on Windows PowerShell 5.1 does not
follow, so the install fails on windows-2025, windows-2025-vs2026 and
windows-2022. The release anchors on that page also lost their dots
(#7040---aug-11-2026), so the old parser matched nothing.

Use the canonical URL without the trailing slash and read versions from
the changelog anchors (#std-label-7.0.40-changelog), which keep the
dotted version. Also pick the highest version rather than the first on
the page, and fail with a clear message when nothing parses.

* Resolve MongoDB version from the downloads feed instead of the docs page

Addresses review feedback. Scraping the release-notes page has now broken
twice: the URL with a trailing slash answers 308 Permanent Redirect, which
Invoke-WebRequest on PowerShell 5.1 does not follow, and the release anchors
lost their dots so the parser matched nothing.

https://downloads.mongodb.org/current.json lists the newest release of each
supported branch, so it is not subject to the markup and URL changes that
broke scraping.
