docs: fix broken internal anchors across documentation

[supunyasanthaofficial]

Motivation

While running the documentation build locally, I noticed several broken internal links reported by Docusaurus. This PR fixes those links so they point to the correct sections.

Changes

• Fixed the AlertButton anchor casing in alert.md.
• Updated the interpolate() link in animations.md to point to AnimatedValue.
• Corrected the iOS switch prop anchor to match the generated heading ID.
• Fixed the transform props link in image.md to point to the correct transform section.
• Removed outdated #content anchors left over from Docusaurus v1.
• Updated the SectionList renderItem anchor to match the generated heading ID.
• Fixed the Codegen Typings link in fabric-native-components.md.
• Updated the Fast Refresh link to point to the current Dev Menu section.
• Corrected the Hermes and build variants anchors to match their headings.
• Backported the fixes to the versioned documentation for React Native 0.77 through 0.87.

Test Plan

• Ran ESLint.
• Ran prettier --check.
• Ran the Docusaurus production build and confirmed that the 13 broken anchor warnings were resolved.
