docs: Add Verito Digital to the support list

[itay-grudev]

Thank you for considering us.

Hi @itay-grudev , thanks for this.

I'm looking at the instructions on adding to the Support page (https://github.com/cloudnative-pg/cloudnative-pg/blob/main/SUPPORT.md)

Specifically, item 3.

Website Link: Include a link to your homepage or a dedicated landing page that explicitly mentions CloudNativePG support and includes at least one link back to cloudnative-pg.io.

I see that the linked page does not link back to CNPG.
To be fair, I note that two companies listed in the support page fail to link back to CNPG:

• B1 Systems GmbH
• EDB (heh 😬 )

[EDIT]: actually B1 Systems does link back. See the discussion around PR #252
So, I think the requirement is serious.
And this leaves EDB as the only violator.

I'd like @gbartolini and @FloorD to weigh in. Is this condition a stopper? If so, what do we do about the providers above?
Perhaps, Itay, a link back can be added to the page? That would earn my approve right away.

[itay-grudev]

Of course, I don't mind linking back. I'll add that right away.

@jsilvela The Learn More link at the very top of the page now links back to https://cloudnative-pg.io/.

Also don't reconsider that rule. If not anything else, links back to the CloudNativePG website boost its search engine scoring.
