docs: drop the URL redirects for the moved pages

Review call by the maintainer. The docs site's URLs are days old (the
/v2/ book shipped just before 2.0.0b1) and v2 is a beta, so there is
nothing meaningful to keep alive at the 28 moved pages' old URLs.
Remove the mkdocs-redirects plugin, its dependency, and the 28-entry
redirect map. Anyone holding a days-old deep link lands on the themed
404 page, which carries the full navigation.

The mkdocs-material floor bump that arrived in the same dependency
commit stays: navigation.path is enabled in mkdocs.yml and genuinely
requires 9.7.0.
