Subject: [PATCH] vimPlugins.blink-cmp: fix runtime version detection error

The plugin fails to load in neovim because it cannot detect the git tag
used during build time. Add patch to force using src.tag instead of
runtime detection, preventing the error:
"Detected an out of date or missing fuzzy matching library. Can't
download from github due to not being on a git tag..."
