Fixes eslintrc warning for no-nested-ternary

[adityathakurxd]

Noticed, if you create a new repository using the template, it throws an error when trying to deploy to Vercel.

It can be locally reproduced by running the command - yarn run build

ERROR in [eslint] .eslintrc:
        Configuration for rule "no-nested-ternary" is invalid:
        Severity should be one of the following: 0 = off, 1 = warn, 2 = error (you passed '"warning"').

Have created a fix for the same as suggested in the message.
