Description

This PR adds functionality to automatic set target="_blank" rel="noopener noreferrer" when href is an external URL.

<PrismicLink href="https://example.com">External</PrismicLink>
// <a href="https://example.com" target="_blank" rel="noopener noreferrer">External</a>

This behavior applies to both the href and field props. In the following example, assume doc.data.linkField resolves to an external URL.

<PrismicLink field={doc.data.linkField}>External</PrismicLink>
// <a href="https://example.com" target="_blank" rel="noopener noreferrer">External</a>

target and rel can always be overriden by passing these props directly.

<PrismicLink href="https://example.com" target={undefined}>
  External
</PrismicLink>;
// <a href="https://example.com">External</a>

<PrismicLink href="https://example.com" rel="help">
  External
</PrismicLink>;
// <a href="https://example.com" target="_blank" rel="help">External</a>

This functionality was intended to ship with the initial <PrismicLink> releaes, but it was accidentally left out.

Checklist:

• [x] My change requires an update to the official documentation.
• [x] All TSDoc comments are up-to-date and new ones have been added where necessary.
• [x] All new and existing tests are passing.
