Handle Russian and Ukrainian plurals

[tunetheweb]

Fixes #1968 using plural-ru function. Note this is not available as an importable function so added code directly to our code base (checked the licence first).

@dtikhonov can you confirm I've used the right words?

English word	ends in 1 (except 11)	ends in 2,3 and 4 (except 12, 13, 14)	else
chapters	глава	главы	глав
contributors	участник	участника	участников
people	человек	человека	человек

It does look like we used "главах" below but Google Translate didn't come up with that at all so I guess double check that?

@tymosh does Ukrainian follow the same rules? Should we do the same for those templates?

Hi @bazzadp. Yes, the same mechanism works for Ukrainian:

English word	ends in 1 (except 11)	ends in 2,3 and 4 (except 12, 13, 14)	else
chapters	розділ	розділи	розділів
contributors	контриб'ютор	контриб'ютори	контриб'юторів
people	людина	людини	людей

I will also need to check sentences for correct words endings in context.

Thanks @tymosh . Added those in the last commit if you wanna double check.

Also added test site here: https://20210204t112250-dot-webalmanac.uk.r.appspot.com

Thanks! Here's another thing: there are different word endings for "contributors" in constructions "124 contributors" and "5 of 124 contributors" in Ukrainian. Is there any way to do that?

Yes and have this working now. Take a look at the latest code. Can also view it here: https://20210204t153224-dot-webalmanac.uk.r.appspot.com

@dtikhonov I presume this is the same in Russian? Can you review the latest code?

Looks good!
