Description The breadcrumbs component represents a list of links showing the location of the current page in the navigational hierarchy.

Requirements To be able to implement this component, some extra requirements were needed:

• The @types/jest library was added so we can start to name test files with the extension .tsx, which is more correct.
• Updated spacing values in the design system to match the current specifications.

Closes #1488

[Mil4n0r]

Currently, accessibility tests are not passing due to the same reason they weren't initally passing for Header and Footer, in this case the nav tag is being repeated in the same page.

We should create a disabledRules.js file inside lib/test/accessibility/specific/breadcrumbs similar to the one existing in the header but with only the "landmark-unique" rule as exception.

It should be added to both the Story file and the Breadcrumbs.accessibility.test that should be created before merging this PR.
