Subject: [PATCH] varPop doc latex formula added

- There is a latex formula in the documentation of the [covarPop](https://clickhouse.com/docs/en/sql-reference/aggregate-functions/reference/covarpop) method, which is quite similar to varPop method.

- In Russian docs there are formulas both for [varPop](https://clickhouse.com/docs/ru/sql-reference/aggregate-functions/reference/varpop), and [covarPop](https://clickhouse.com/docs/ru/sql-reference/aggregate-functions/reference/covarpop).

Therefore, for consistency, it is suggested to add formula here too.
