Describe the solution you'd like

There are a few steps required

• Create a new directory for it. An example is the /Login directory https://github.com/Project-Reclass/toynet-react/tree/main/src/Login
• Create the new page. You can use the Login directory setup as an example
• Add a new route /signup. Example for login page https://github.com/Project-Reclass/toynet-react/blob/main/src/App.tsx#L108-L112
• Make sure its lazily imported like this https://github.com/Project-Reclass/toynet-react/blob/main/src/App.tsx#L30

Note: we don't have any backend API so don't worry about actually creating a user. Just create the skeleton of the page :)
