Update readme.md about maxDuration (#2792)

* Update readme.md about maxDuration

I think we can remove this warning section since that value in  `.json` has been changed to 10 by default nowadays?

* Update readme.md

remove related section in self deployment section as well

* docs: add inverse maxDuration warning

-> If you are on the [hobby (i.e. free)](https://vercel.com/pricing) Vercel plan, please make sure you change the `maxDuration` parameter in the [vercel.json](https://github.com/anuraghazra/github-readme-stats/blob/master/vercel.json) file from `30` to `10` (see [#1416](https://github.com/anuraghazra/github-readme-stats/issues/1416#issuecomment-950275476) for more information).

 Since the GitHub API only allows 5k requests per hour, my `https://github-readme-stats.vercel.app/api` could possibly hit the rate limiter. If you host it on your own Vercel server, then you do not have to worry about anything. Click on the deploy button to get started!
 
 > **Note**
 > Since [#58](https://github.com/anuraghazra/github-readme-stats/pull/58), we should be able to handle more than 5k requests and have fewer issues with downtime :grin:.
 
+> **Note**
+> If you are on the [Pro (i.e. paid)](https://vercel.com/pricing) Vercel plan, the [maxDuration](https://vercel.com/docs/concepts/projects/project-configuration#value-definition) value found in the [Vercel.json](https://github.com/anuraghazra/github-readme-stats/blob/master/vercel.json) can be increased when your Vercel instance frequently times out during the card request. You are advised to keep this value lower than `30` seconds to prevent high memory usage.
