Update browse Git repo URLs in component READMEs

There are two more mentions in the repository that mention cgit.drupalcode.org. Perhaps we can update these as well?

1. // List of unicode-encoded characters that were allowed in URLs,
         // according to link module in Drupal 7. Every character between ¿
         // and ÿ (except × × and ÷ ÷) with the addition of
         // Œ, œ and Ÿ.
         // @see http://cgit.drupalcode.org/link/tree/link.module?h=7.x-1.5-beta2#n1382
   

   \Drupal\link\Plugin\migrate\process\FieldLink::canonicalizeUri()

2. Previous versions of drupal-scaffold (see community project,
   [drupal-composer/drupal-scaffold](https://github.com/drupal-composer/drupal-project))
   downloaded each scaffold file directly from its distribution server (e.g.
   `https://cgit.drupalcode.org`) to the desired destination directory.
   

   ./composer/Plugin/Scaffold/README.md

This patch should fix the issue.

@shubham.prakash Thanks for providing a new patch! Can you add an interdiff next time to make it easier to review the patch? See https://www.drupal.org/documentation/git/interdiff for more information

Gitlab uses a different fragment structure to reference line numbers:

cgit: #n1382
Gitlab: #L1382

This fragment should be updated to keep the line reference intact.

Thanks for the review. This patch should fix the issue.

Committed 188c37b and pushed to 8.8.x. Thanks!
