chore: update dependencies and improve script execution condition

- Updated vitepress from version 1.5.0 to 1.6.3 in package.json and pnpm-lock.yaml.
- Updated various dependencies in pnpm-lock.yaml including @docsearch/css, @docsearch/js, @iconify-json/simple-icons, @shikijs/core, and others to their latest versions.
- Modified install_adventurelog.sh to improve script execution condition by allowing it to run when piped input is detected.
