Update release-notes.R to bump version fields at release time (#1944)

Extends the release notes script to also update `version` in
`_quarto.yml` (to the released version) and `_quarto-prerelease-docs.yml`
(to the next prerelease). This automates the version bump that was
previously a manual step, ensuring the `prerelease-docs-url` shortcode
resolves blog post links correctly after merge to main.

+# Update version for prerelease-docs-url shortcode -------------------------

+# prerelease branch means it propagates to main when prerelease is merged,
+# so the shortcode resolves blog post links to quarto.org.
+# _quarto-prerelease-docs.yml is bumped to the next prerelease for the
+# announcement banner on the prerelease site.
