NASHA available storage capacity not relevant

[fzindovh]

Issue

Available storage capacity are not up to date and do not list legacy capacity.

Proposal

Add a mention about legacy capacities and a link to the configurator

[Izaia64]

We don't sale anymore the legacy capacity (<3TB). These capacities are not shown in the order configurator. That is on purpose

[fzindovh]

I know that. My proposal is to stop listing capacites on docs side to avoid inconsistency.

1. a link to the configurator for customers who want to know what capabilities are offered
2. a reference to other capabilities (but not listed)
