docs: send Docker Pro upgrades to the pricing page (#25992)

## Summary

Support was sending customers to Docker Home Billing, then the product
catalog, then **View plans** to upgrade to Docker Pro. The way to
upgrade to Pro is the [Docker pricing
page](https://www.docker.com/pricing/): select **Buy now**.

This change puts that path in three owned CTAs and retargets inbound
upgrade links so they land on those CTAs instead of restating the same
sentence.

**Why 3 copy locations:** Docker Pro purchase copy should live only
where people (and Gordon) look: the Docker plans page, the subscription
FAQ, and Manage plans (the upgrade landing page, including
`/subscription/upgrade/`). Repeating a Pro → pricing aside on every
overview and feature page would drift when Billing changes the flow.
Three sentences are the maintainable set.

**Why silent links:** `/subscription/` and the plans index currently
imply every plan is purchased from Docker Home Billing / the product
catalog. Those pages should point at Manage plans / Docker plans instead
of restating Pro copy. Hub pull-limit troubleshooting and Build Cloud
cache "upgrade your subscription" sent Personal users to
`manage.md#upgrade-plans` (catalog). Retarget those links at the Docker
plans page so they pick up the owned CTA without a fourth/fifth copy.
