Add support for storing icon SVGs as strings #37

[blueputty01]

Stores html of SVG icons rendered in the search interface

Resolves #37

Proposes lighter solution in parallel to #39.

Specifically, this PR proposes:

• Updating @sanity/pkg-utils due to issue with link-watch on Windows preventing local dev testing
• Copying preferred samples in docs from #39
• Modifying line break eslint and prettier configs for return character causing conflicts on Windows
• Storing html of SVG icons through the already-rendered elements in the search interface
