* Add a dedicated `vim.yank.background` theme color for the yank
highlight, which was previously hardcoded to
`editor.document_highlight.read_background`.
* When a theme doesn't define `vim.yank.background`, it falls back to
`editor.document_highlight.read_background` for backwards
compatibility.
* The VS Code theme importer maps `editor.rangeHighlightBackground` to
this new color.
Release Notes:
- Added configurable `vim.yank.background` theme color for vim yank
background highlight
