Fix lychee.toml syntax error - use correct remap format

Fixed TOML parse error: "invalid type: map, expected a string"

The remap feature in lychee uses a simple key-value mapping table,
not an array of tables with pattern/replace fields.

Changed from:
  [[remap]]
  pattern = "^/docs/(.*)$"
  replace = "file://./docs/$1.mdx"

To:
  [remap]
  "/docs/" = "file://./docs/"

This maps all /docs/* URLs to the local docs/ directory, and lychee
will automatically try common file extensions (.md, .mdx, etc.).
