Remove nprogress + use next-nprogress-bar

[carletex]

When we migrated to the App Router #535 we switched from https://www.npmjs.com/package/next-nprogress-bar to https://www.npmjs.com/package/nprogress + creating a custom integration with the App Router.

We already had an issue with external _blank links #909 and now I realized that we have the same problem with hash links (#section). The progress bar will start to load (it shouldn't do anything)

One solution will be to just parse the #links and fix it, but created this PR with another alternative: moving back to next-nprogress-bar which has been updated and supports the App Router nicely. Under the hood it does the same thing that we are doing, but it's handling some stuff a bit better. So it'll be moving custom logic to an external library.

Happy to close this, just wanted to hear your take on it.

Thanks!!

Agree let's return to next-progress-bar since it's up to date. Working great for me!

Makes sense! Also seems to nicely work with a tags(not showing the loader)
