Redirect the "Get started" links from pricing page

[Adal3n3]

Redirect the "Get started" links from the https://about.codecov.io/pricing/ site to "the last visited" org, not the personal-org.

• The confusion starts from I'm on the Turing-Corp plan page > click on Learn more, before upgrading my plan it brings me to the marketing pricing side > click on "Get started", it takes me to my personal org. The expected link should take me to Turing-Corp plan page. @spalmurray will investigate the redirect link to "the last visited" org.
