Percy examples combination - base/code

[jmuzina]

Combines base/code examples.

Inline & block were moved into a new base/code directory so that they could be combined in base/code/combined. So I also added redirects to keep their old links supported.

Depends on #5142 (includes its code)

QA

• Review base code combined examples
• Review base code inline docs; they have been updated to remove the old dark mode code-inline-dark embed.
• Verify redirects
  • https://vanilla-framework-5143.demos.haus/docs/examples/base/code-block redirects to https://vanilla-framework-5143.demos.haus/docs/examples/base/code/block
  • https://vanilla-framework-5143.demos.haus/docs/examples/base/code-inline-dark redirects to https://vanilla-framework-5143.demos.haus/docs/examples/base/code/inline?theme=dark
  • https://vanilla-framework-5143.demos.haus/docs/examples/base/code-inline redirects to https://vanilla-framework-5143.demos.haus/docs/examples/base/code/inline
• Make sure the embedded code docs are not missing / failing to embed due to the link path changing
