Broaden format constraint to include numerical digits

Seems there are games listed in IndieMag whose game IDs contain numbers, especially sequels, e.g. Divinity: Original Sin 2 (Q20899735) → divinity-original-sin-2; Axiom Verge 2 (Q108061178) → axiom-verge-2. The format constraint should probably be adjusted to [a-z0-9]+(-[a-z0-9]+)* to account for this. Btcprox (talk) 03:31, 11 September 2021 (UTC)

@Btcprox: you are right. Usually, I start with a rather contrained regex and I broaden it after some time in order to cover the items that do not match the format constrain. So for now I added digits only for the second word and further (not the first). Let us see whether it is enough. Pamputt (talk) 05:54, 11 September 2021 (UTC)
