chore(deps): bump tmp and @contentful/app-scripts in /apps/remote-mcp (#10207)

Removes [tmp](https://github.com/raszi/node-tmp). It's no longer used after updating ancestor dependency [@contentful/app-scripts](https://github.com/contentful/create-contentful-app/tree/HEAD/packages/contentful--app-scripts). These dependencies need to be updated together.


Removes `tmp`

Updates `@contentful/app-scripts` from 2.5.5 to 2.5.6
