Re enable bot restriction and add .nojekyll for github pages (ethereum-optimism#1111)

* re-add bot restriction

* Update .npmrc to use variable syntax for NPM token and clean up CircleCI config by removing unused environment variables and commands.

* add .nojekyll file to prevent Jekyll processing on GitHub Pages

* Enhance CircleCI config by adding environment variables to prevent misuse of GitHub tokens and improve security.
