Rebuild pkgdown site for v2.5.1

[pedrohcgs]

Summary

• Rebuild the complete pkgdown site after cleaning generated output.
• Generate and commit the complete favicon and web-manifest set in both pkgdown/favicon/ and docs/.
• Add a local pkgdown head-template override that corrects the SVG favicon MIME attribute.
• Remove stale generated assets, including the unreferenced Bootstrap 5.3.8 dependency tree.
• Keep package source metadata at release version 2.5.1.

Why

The package source is version 2.5.1, but the committed website had been generated for 2.5.0. The first rebuild synchronized the site version; this follow-up also makes favicon generation reproducible and ensures obsolete output is not carried forward by incremental builds.

Impact

This PR changes generated website files plus their favicon and head-template sources under pkgdown/. No R source code, tests, or package version metadata are changed. Removing obsolete generated files reduces the published and repository footprint without changing page behavior because the retained site has no references to them.

Validation

• Clean pkgdown build completed successfully in an isolated checkout.
• Confirmed package version 2.5.1 before the build.
• Full unit suite: 1,784 passed, 0 failed, 0 warnings, 8 documented skips.
• Parsed all 58 generated HTML files with no parse errors.
• Verified every local HTML and CSS asset reference resolves.
• Verified all 253 search-index entries and all 55 sitemap URLs resolve.
• Verified both web-manifest icons exist and all 55 normal pages use image/svg+xml for the SVG favicon.
• Confirmed no Bootstrap 5.3.8 files or references remain.
• Confirmed the 2.5.0 changelog entry remains only as release history.

Existing documentation warnings

The build still reports missing alt text for existing README badges and several existing vignette images. These warnings predate this release-site update and do not affect package runtime behavior.
