fix(docs-infra): use relative URLs for internal links on error pages (#40881) Previously, some of the links on the error pages had URLs prefixed with `https://angular.io/`. This caused them to be treated as external URLs, which had the following downsides: - Links would always point to `angular.io` instead of the same version as the error page (e.g. `next.angular.io` or `v11.angular.io`). - Dgeni would not be able to check that the URLs are valid (i.e. point to existing pages). - An external link icon would incorrectly be shown next to the links on `angular.io`. This commit fixes the links to use relative URLs. PR Close #40881

Check that the name and selector are correct. If the component is from a different module or import, check that the component is exported from its origin module and imported into the correct `*.modules.ts` file, and declared in the imports list.

If this does not resolve the error, check the imported libraries for any recent changes to the exports and properties you are using, and restart your server.
