Replace Zendesk support portal links with support@pulumi.com (#20868)

* Point paid-plan email support at support@pulumi.com

The "Direct email support" bullet on /docs/support/getting-support/ linked
to the Pulumi support portal, which reads as a contradiction: the bullet
promises email and then sends the reader to a portal. Link the address
directly instead. Requested by Kelsey Dirks, who notes we're moving away
from the portal going forward.

* Swap remaining Zendesk portal links for support@pulumi.com

Kelsey confirmed the security page and the onboarding edition guide are
the two other spots that point at the Zendesk portal and need the same
treatment as the getting-support bullet. The rest of the site's
support.pulumi.com links route through HubSpot and stay as they are.

On the security page, "file an issue with" becomes "contact ... at",
since emailing support isn't filing an issue.
