Resolving Missing ShortId in the Database

[Abh-I-seK]

Describe the bug
After shortening a URL, we get an URL in form of https://urlsrt.vercel.app/data.
Now if we pass a arbitrary value in place of data then it shows the following.
In the example below, I used the URL : https://urlsrt.vercel.app/111222

So, I think if in getSpecificUrl() (in server/controller/urls.js)
once we find the data based on shortId then check if its null. If null, then we will redirect the user to an 404 page which will say that
"This link does not exist".

And will also add link to navbar, which will redirect to homepage.

Could you please assign this issue to me under GSSOC 24.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://urlsrt.vercel.app/111222

Great, Assigning this issue to you now.

You are implementing frontend and backend both right?
The UI should be responsive also right?
