chore(landing)(deps): Bump the astro group across 1 directory with 3 updates

[dependabot]

Bumps the astro group with 3 updates in the /landing directory: @astrojs/rss, @astrojs/sitemap and astro.

Updates @astrojs/rss from 4.0.18 to 4.0.19

Release notes

Sourced from @​astrojs/rss's releases.

@​astrojs/rss@​4.0.19

Patch Changes

• #17209 fbcfa03 Thanks @​matthewp! - Hardens RSS feed generation by escaping the source and enclosure item fields. These fields are now serialized as structured XML values, ensuring that special characters in values like source.title and enclosure.type are always treated as text rather than markup, consistent with how other feed fields are handled.

Changelog

Updates @astrojs/sitemap from 3.7.2 to 3.7.3

Changelog

Sourced from @​astrojs/sitemap's changelog.

3.7.3

Patch Changes

• #16837 783c4a6 Thanks @​jdevalk! - Improves <lastmod> accuracy in the sitemap index. Each <sitemap> entry in sitemap-index.xml is now stamped with the most recent lastmod of the URLs in the child sitemap it points to, instead of repeating a single global date on every entry. When a child sitemap has no per-URL lastmod, the entry falls back to the lastmod option as before. This gives search engines a per-file freshness signal, so they can tell which child sitemaps actually changed without refetching all of them.

Updates astro from 5.18.1 to 5.18.2

Changelog

Sourced from astro's changelog.

5.18.2

Patch Changes

• #16813 8f7d8c4 Thanks @​matthewp! - Populates styles in the SSR manifest for prerendered routes. Previously, prerendered routes had styles: [] in the manifest, making it impossible for workers or middleware to discover which CSS files a prerendered page uses.
