website: rephrase several hundreds of packages

The phrase "Supports several hundreds of packages" is unusual to hear in
English (or at least American English). The more common alternatives are
"Supports several hundred packages" or "Supports hundreds of packages".
The latter sounds like a larger amount, so change the phrase to that.
